Understand that if the HDD has bad electronics, anything you plug it

I always keep an old desktop machine around as my "workbench".  If I 
smoke a HDD port, the motherboard, or a whole machine, that would be 
inconvenient, but not a show-stopper.  A workbench, a cache of used/ 
spare parts, and a few of the right tools make trouble-shooting far easier.

No, But I got myself a meeting with my friend who runs a laptop repairing shop,
who is willing to give me access to his hdd casing.
I will take my girlfriend's dell laptop, I have already installed debian in it.

Hopefully I manage to get the hdd repartitioned. Will keep everyone posted.

Although I am a CS student, I should better wait, and not put my friend's hdd
in jeopardy. I will report what happens when I get my hands on the
casing and connect
the broken hdd to a debian box.

My next step would be to download, burn, and run the HDD manufacturer's 
diagnostic tool.  Again, beware that bad HDD electronics can damage 
whatever you plug the HDD into, so choose your Guinea pigs carefully:


- If the computer won't POST or the tool  won't run with the HDD in an 
external case/ dock, try another cable, case/ dock, and/or computer. 
Try new and old computers and/or equipment.  Think carefully before 
trying an internal connection.  If you can't get the tool to work after 
trying many combinations, then the HDD electronics are toast.  Get 
another drive.


- If/ when you can run the tool, perform all available tests.  Next, 
regardless of the test results, wipe the entire drive (fill with zeros; 
750 GB will take a long time).  Use a bootable Linux CD or USB drive and 
dd if the HDD diagnostic tool doesn't have this feature (some lack it). 
 Then run the tool and all the tests again.  If the drive passes 100%, 
you're in luck.  If not, get another drive.



If you end up getting a non-new replacement drive, perform the above 
steps on it.



Once you have a known good drive, plug it into your laptop and see what 
happens.  If it works, you're back to the partitioning question.  If 
not, the next step will be to trouble-shoot the laptop.




I appreciate the fact that you are taking time and replying me. Means

It sounds to me like you have some issues between your two sets of ram,
the 8G stick and the 2x4G sticks.  Is there a difference in
timings/speed/voltage?  I've never put much stock in people saying that
you shouldn't mix different types of ram if the price is right, but you
might need to change around the placement order.  Assuming the
motherboard supports dual-channel ram, I'd make sure you have the 2x4G
sticks paired up and the 8G stick on its own channel.

According to page 16 of the manual you have an unsupported memory
configuration:
http://download.gigabyte.us/FileList/Manual/mb_manual_ga-970a-d3p_e.pdf


If this combo will ever work, the first step is to verify the 8GB stick
is in one channel and the two 4GB sticks in the other.  If you still
don't see all 16GB then disable rank interleaving.  If that doesn't fix
it, disable channel interleaving.  If that doesn't fix it, you may be of
luck, and will need to either swap the 8GB stick for a pair of matched
4GB sticks, or acquire another identical 8GB stick.

images that play nicely with revision control?

[Hendrik Boom]

I'm looking for a file format for images that plays nicely with revision 
control. Ideally I'd like to edit them while seeing what I'm editing, 
whether it's a line drawing (like inkscape) or a pixel map.

And I'd like to keep the whole thing under revision control (like 
monotone, or git, or such.  Currently I use monotone).

But any kind of compressed file format is probably not going to cut it.  
Revision control seems to be designed for program text, with lots of 
newlines in stable places.

If all else fails, and I get desperate I could even store my images as 
programs in, say, Scheme or C or some such, and run the code to see the 
image.  But that would make editing difficult.  And in that case, I'd 
like recommendations to graphics libraries that can output to a variety 
of formats, such as onto the screen, into a jpeg file, to svg or html 
format, or some such.

I would definitely prefer not to write a whole new image editor from 
scratch.

I think that doesn't exist. At least not for all kind of images.
SVG is basically an XML file. There you can at least compare the xml
content. But that however is also very tricky, you might need something
which converts it first into canonical xml and the compare/store it.
But that is only efficient for vector images. For bitmap images that
wouldn't work.

That approach is close to what adobe does. They basically have a master
image. They store with that image every change. That is how Lightroom
handles changes. This of course can be very demanding on cpu/gpu. Because
everytime you load the picture you have to apply all the changes to the
master, render it and display it.

That page just tells you how to install dual-channel DDR3 sticks. Again, 
the BIOS detects the full 16G. This shows that the setup does work with 
the board.

GRUB seems to confuse md boot device and its spares

[Ari Epstein]

I'm having peculiar difficulties getting grub to boot from a RAID1 md.  The
machine has four drives, and the md (which contains / as well as /boot) is
on sdc1 and sdd1.  sda1 and sdb1 were once configured as spares though at
the moment they are not connected to the raid at all.  The grub.cfg has the
correct UUID for the md.
Today I upgraded to the latest 7.4 kernel (3.2.54-2) and rebooted.  The
system appeared to boot correctly, but I noticed the kernel is the same one
that was running before (3.2.41-2).

The output from update-grub suggests it is detecting older installations of
debian, which I suspect are in sda1 and sdb1.  I am guessing that somehow
grub is loading from those unused spare partitions instead of the ones in
active use, but could use some help confirming this/understanding how I can
fix it.  Any ideas?

Here's the update-grub output:

I'm running Jessie on an AMD64 Gigabyte 970A-D3P board with an FX6100

a good price on it, much cheaper than adding 2x4G) which resolved the
thrashing problem.

The BIOS shows I have 16G but free shows only 12G. I also ran free on
a machine with 2x8G DDR3 running Wheezy and it showed 16G when I ran
free. This suggests that the kernel is handling 16G (as one would
expect) in the general case and the issue is likely due to my setup.

Since the BIOS shows the full 16G, the problem doesn't seem to be on
the mainboard. Is there an issue with running interleaved and
non-interleaved RAM together on the Jessie kernels?



It sounds to me like you have some issues between your two sets of ram,
the 8G stick and the 2x4G sticks.  Is there a difference in
timings/speed/voltage?  I've never put much stock in people saying that
you shouldn't mix different types of ram if the price is right, but you
might need to change around the placement order.  Assuming the
motherboard supports dual-channel ram, I'd make sure you have the 2x4G
sticks paired up and the 8G stick on its own channel.


According to page 16 of the manual you have an unsupported memory
configuration:
http://download.gigabyte.us/FileList/Manual/mb_manual_ga-970a-d3p_e.pdf


If this combo will ever work, the first step is to verify the 8GB stick
is in one channel and the two 4GB sticks in the other.  If you still
don't see all 16GB then disable rank interleaving.  If that doesn't fix
it, disable channel interleaving.  If that doesn't fix it, you may be of
luck, and will need to either swap the 8GB stick for a pair of matched
4GB sticks, or acquire another identical 8GB stick.


That page just tells you how to install dual-channel DDR3 sticks. Again,
the BIOS detects the full 16G. This shows that the setup does work with
the board.




"Detected" and "Working" memory are two entirely different things.  It 
is perfectly possible for your BIOS to detect 16GB, but 4GB of it not 
work properly.


Both Stan and Efraim have good comments.  I suggest you follow them.

Rather than blow away Android completely at this point, today, you might want 
to look at the Ubuntu touch
offerings which may allow you to dual-boot. 

[This only because Debian is more widely focussed on all sorts of things other 
than
wholly on ARM tablets, because Ubuntu are pushing for this Ubuntu touch 
infrastructure at the moment, 
and because Ubuntu are certifying on various hardware - the likelihood is that 
Debian can't match 
Ubuntu today on that platform but may well at some point.]

ARM tablets are a problem because of non-free blobs of firmware, SOC hardware 
and closed components
- it's getting better and ARM is rapidly becoming more widely supported but 
it's not as straightforwardly
mainstream as the PC architecture.

Hope this helps,

AndyC

No.



Incorrect.


Sata supports hotplugging. The worst that will happen is some
controllers will not recognize devices after hotplugging due to lack of
firmware configured detect devices after an initial post bus scan.


Only if the device and controller fully support hotplugging (surprise - 
some DO NOT!) AND the drive is working properly.  Clearly the drive is 
NOT working properly.

It depends. If your hard drive is externally accessible it can't hurt
anything. If your hard drive is under panels that also protect ram or
any other pcbs, you generally shouldn't run system with those covers
missing.


Again, incorrect.  If the drive is damaged electronically, ANYTHING it 
is plugged into can be damaged.  And if either the drive or the 
controller do not support SATA hotplugging, either (or both) can be 
damaged by hotplugging the device.

Completely wrong. Wikipedia has it in fairly simple words:
http://en.wikipedia.org/wiki/Serial_ATA#Hotplug



Again see above.


Also the first twenty or so articles on Google all confirm at a glance
that hotswap is supported by sata intrinsically, and any problems are
the result of software or firmware bugs failing to trigger hotswap
events properly.

Please to not spread bad or wrong information.



Yes, please do not do so.

Do you believe EVERYTHING you read on the internet?

That's what I suspected.  But I asked in the hope that there was

And XML can be difficult to do revision-merging on, even if furnished 
with lots of newlines -- what the merge algorithm considers a perfectly 
acceptable merge may end up violating XML's large-scale bracket matching.
Which means the user gets to worry about how his picture is coded, in 
exasperating detail.  But with some restricted limited-nesting XML files 
it might be made to work.

But I can imagine bitmaps to be mergable, if not compressed, and if enouth 
newlines are inserted in standard places, such as between scan lines.
Still, better techniques ought to be possible.

So the change could sconsist of adding a bunch of code into the existing 
file.  And theh reverse change would consist of deleting it.  Maybe non-
conflicting merging would even work.  But the proper test for conflicts 
would be whether the two changesets affected the same part of the image.

Unless someone comes up with something else, it looks like a topic for 
further research.

And about compression?  It may turn out that the space saved by not 
duplicating parts of an image  that didn't change may outweigh the space 
lost by not compressing.

It is the maildrop invocation (via pipe) that causes the problems. One 
obvious mistake I did was to leave the -d ${recipient}, while I need to 
call maildrop with -d ${user}, since I have system not virtual users. 

The correct line in master.cf should look like this:

maildrop  unix  -   n   n   -   -   pipe
  flags=DORX user=mail argv=/usr/bin/maildrop -d ${user}

Once I fixed that I hit another issue:


Feb  9 18:19:15 sid postfix/pickup[6738]: 7FF70C0DF3: uid=1077 from=
Feb  9 18:19:15 sid postfix/cleanup[6744]: 7FF70C0DF3:

(temporary failure. Command output: ERR: authdaemon: s_connect() failed: No 
such file or directory /usr/bin/maildrop: Cannot set my user or group id. )


As far as I can tell this is because maildrop is installed setgid and 
not setuid:

$ ls -l /usr/bin/maildrop
-rwxr-sr-x 1 root mail 206940 feb  1 19:44 /usr/bin/maildrop

chmod u+s works (tested), but I'm not very happy with it, even though 
maildrop's documentation claims this is safe as it will immediately drop 
privileges to the user specified by the '-d' option.

Another option is to invoke it as user 'amp' (also tested) via the 
'user=' directive in master.cf, but this can only work as long as I'm 
the sole user.

Since this endeavor is important only in the context of eventually 
running a public facing postfix -> maildrop setup I'm not very fond of 
any of these two workarounds.

Kind regards,
Andrei

You didn't say much about your actual drawing mixture.
You might get some ideas by looking at details of *EARLY*

I think the OP wants to know on which particular core the script is

AH!  The days before widespread revision control!

HPGL looks like it would fit the bill, for line drawings, anyway. If I 
could get an off-the-shelf editor to read it and write it, anyway. It 
dose seem to be more like object code than source code, so to speak.

It would work with revision control if I could put in newlines instead of 
semicolons. Or modify the revision control system to accept semicolons 
and treat them as it now handles newlines.  Really, it should be possible 
for a revision control to understand file types and know what's special 
about them.

One workaround is to write some code that transforms between a revision-
friendly HPGl and regular HPGL in both directions, to use the revision-
friendly HPGL as checked-in source code, and to turn an existing editor 
into one for this format by a shell command that converts back and 
forth ...

Come to think of it, this might work with a lot of the other graphics 
file formats.  As long as they don't contain arbitrary identifiers that 
change with every edit. I must investigate.

I've faced the same problem with word-processor file formats, actually.  
At the moment the solution seems to be systems like markdown and 
asciidoc.  But it's easier there because marked-up ASCII text is a lot 
closer to the format in which the final document is presented.  It's 
still text, after all.

There's opportunity for some low-level research here.

For bitmap images, you *could* resort to storing them in PBM format -
which happens to be pure text and easy to parse[1].  The netpbm package
contains tools for converting to/from a plethora of formats. And to do
basic command-line manipulation of images.

For viewing the image, the normal Gnome tools understand PBM -
e.g. eog will happily show them, and nautilus will show you
thumbnails.  Not sure about other file managers...

Personally I'm dubious if using `jessie` instead of `testing` atm should
even work - considering that it is basically testing for the time being.

Embed text into video file and search video from text?

[Nick Lidakis]

I have a text file that includes time stamps. I also
have video (H.264, MPEG-4 or JPEG stills) recorded from
an IP camera. I'm trying to find a way to jump to certain
points of he videos based on events in the text file at hand.
The text file is generated from an RS-232 port.


The IP camera, from Axis, has support for dynamic text overlay
but I'm not sure if that could be searched. 


I've tried Google and have not found anything. I was hoping
there was something out there in he scientific realm, i.e.,
video text overlay searchable by event, i.e, temp. change.

http://cdimage.debian.org/debian-cd/7.3.0/i386/iso-cd/

I found only the links until the CD 8.

But the list of md5sum indicates that there are 68 CDs
http://cdimage.debian.org/debian-cd/7.3.0/i386/iso-cd/MD5SUMS

Any tips?

I read "...core #..." as "...the number of cores on the
machine...".  Hm, yes, your interpretation is also possible.

Anyway, is it possible at all to determine the particular core
the current script is running?  I mean, there is one underlying
shell process.  But if the script uses a pipeline, a command that
is not builtin in bash, or just a simple while loop, etc. there
will surely be further (sub)processes.  I doubt they are all
running on the same core.  Therefore the particular core a shell
script is running on doesn't seem to be sensible?

Perhaps the OP wants to use taskset, cpuset and the like.  But
without providing much more details...

Mathias

How to use de "update" CDs?

[Markos]

Hi All,

I'm planning to download the CDs :

http://cdimage.debian.org/debian-cd/7.3.0/i386/iso-cd/debian-7.3.0-i386-xfce-CD-1.iso 



and

http://cdimage.debian.org/debian-cd/7.3.0/i386/iso-cd/debian-7.3.0-i386-CD-2.iso 



to install Wheezy on a laptop.

But I don't know how to use the CDs "Update".
debian-update-7.3.0-i386-CD ...

Please, how do I use these CDs?
 debian-update-7.3.0-i386-CD-1.iso
 debian-update-7.3.0-i386-CD-2.iso
 debian-update-7.3.0-i386-CD-3.iso
 debian-update-7.3.0-i386-CD-4.iso
 debian-update-7.3.0-i386-CD-5.iso
 debian-update-7.3.0-i386-CD-6.iso
 debian-update-7.3.0-i386-CD-7.iso

I put them with additional CDs during installation or use after 
installation?


Thanks for any tip.

Hi Markus,

after installation with the first cdrom, you can add them with the "apt-cdrom" 
command.

However, if you have an internet access, it would be much easier, to install 
all needed packages right from the web. 

You might use then apt-get, aptitude or synaptics. All are great and easy to 
handle tools.

Good luck!

Hans

they just did the version update, give them a couple of hours to push
the updates and rebuild the iso-s on the mirrors.  The link to 7.3.0 is
already dead.
http://cdimage.debian.org/debian-cd/7.4.0/i386/iso-cd/MD5SUMS lists 67
CDs, they should get there soon enough.

With a good speed internet connection, you might be able to use just the 
netinst CD and install the rest from the network.

If you use CDs, you can probably arrange to use just the first xfcd-CD-1.iso to 
install a basic system. A full Debian system
with no access to the network might use all of the CDs / DVDs.

The update CDs are meant to be used to update a system using a previous version 
to the current version - if you had a system
running 7.2 and no network access, you could bring a 7.2 system up to 7.3

Today, it might be worth waiting a day - Debian released 7.4 over the weekend 
and updated install CDs witll shortly be available which will
install 7.4

If you have 7.3 CDs for disk1 and disk2 then once you've got the laptop on the 
'net, you can update immediately to 7.4 without needing any further 
media.

Hope this helps,

AndyC

Not normally needed - see my other message to the list. If you _really_ need
them, then you can use jigdo (Jigsaw download) program to download individual
packages from the internet and stitch them together to form CD / DVD images.

Keeping 400 CDs meant rather a lot of disk space and bandwidth - this way
the people who really need the CDs from 8-40+ can build them individually.

Those with good network access can simply download staraight from the Internet.

While this works, it's suboptimal for a number of reasons, primarily
being inflexible and space wasting.  It's inflexible because should
your needs change (e.g. you run out of space on /opt or /var), you
can't do anything about it other than hairy repartitioning involving
backup and restore of the data.  It's also vastly more complex than
it really needs to be.

I've been bitten by this in the past.  Firstly, when my fixed size
/boot prevented kernel upgrades because two images and initrds would
no longer fit (and the sizes keep getting bigger).  Secondly, when
the rootfs got too small and wouldn't allow package install/upgrade
despite having gigabytes of space on /usr; there's no need to
separate them, and it's much less likely to cause problems if they
are together.  So you're caught between two bad situations:
preallocating sufficient space that you won't be caught out by
size requirements increasing over time, and overallocation of space
which is then wasted pointlessly.

On Linux, there are three possibilities which mitigate all these
things:

1) Use LVM.  You can use the entire drive as a single physical volume
   (PV) and then carve it up into separate logical volumes (LVs).  This
   allows exactly the same strategy as above, but you can start with
   the minimum needed size for each partition and leave the remaining
   space unallocated.  Should you need additional space for any of the
   volumes, you can just extend it on demand.  Downside: space allocation
   is manual and some degree of space wastage still occurs.

2) Use Btrfs.  You can have a single Btrfs volume, and then use
   subvolumes for all the separate parts, divided up exactly as above.
   The subvolumes may be independently snapshotted, backed up and
   preserved.  The rootfs itself can be a subvolume.  The main problem
   here is that Btrfs isn't production ready, so I can't recommend it
   unless you don't care about your data.

3) Use ZFS.  Allocate the drive as a single zpool.  You can then create
   zfs volumes for all the separate bits.  However, you don't have the
   space wastage issues since all the data is in a single pool, and
   you can adjust the size allocations/quotas on demand for each
   individual volume (or leave them unset to give them as much space as
   they can get).  Needs a kernel patch for the zfs driver.  With
   kFreeBSD you can do this natively.  It has all sorts of great
   features which I won't go into here.

I've tried all three.  For Linux, using LVM is easy and can be done
in the installer.  If you reinstall you can keep the LVs you want and
wipe/delete the rest.  For kFreeBSD, you can install directly onto ZFS;
I've been using it for kFreeBSD and native FreeBSD installs, and it's
the best of the lot--hopefully Debian can offer native support for
Linux at some point [currently needs patching, and the patches don't
work with current 3.12 kernels]

Nowadays you can just have / readonly so /usr doesn't need to kept

I don't understand LVM, but I tried to install some distro just to
learn about it, and it would only install using LVM, which meant
that it would only install on the entire hard drive. No partitions,
no Windows, no nothing. I installed it on a second small h/d, and
then I found out that nothing on it was accessible from a normal
Linux installed on a normal file system on sda.  If LVM becomes
the Linux standard, I will have to find a different OS!

Sounds like a bee-in-the-bonnet distro. Normally, LVM volumes map to
partitions, and as long as you have the LVM packages installed on any
Linux system, it will be able to read LVM systems.

As you see here, my main workstation has an LVM partition and a normal
one. I have a bit of a bee in my bonnet about grub, having had several
run-ins with it on various machines, and I trust it about as far as I
can throw the average office building. Hence the separate /boot
partition. Grub does understand LVM natively, but if one day it decides
to play dumb, it is more accessible on its own partition, and can be
more easily held to account with the software equivalent of an axe.

Sounds like a bee-in-the-bonnet distro. Normally, LVM volumes map to
partitions, and as long as you have the LVM packages installed on any
Linux system, it will be able to read LVM systems.

As you see here, my main workstation has an LVM partition and a normal
one. I have a bit of a bee in my bonnet about grub, having had several
run-ins with it on various machines, and I trust it about as far as I
can throw the average office building. Hence the separate /boot
partition. Grub does understand LVM natively, but if one day it decides
to play dumb, it is more accessible on its own partition, and can be
more easily held to account with the software equivalent of an axe.

It was not a weird distro. I don't remember whether it was
RedHat, or SUSE or Fedora, but I'm pretty sure it was one of them.
I found that there is something called lvm2 in my repos, and I
installed it; I don't remember if I still have the other distro on
the second drive or if I blew it away (probable!). But it did
*not* respect available partitions--it wanted the whole
verdammt drive!

I usually use a distro that uses classic grub, and I've never had
a problem with it. I can even boot other distros installed on the
drive from grub.

I remember seeing you or someone writing that multiple partitions
are not useful. I respectfully disagree. Unless someone is storing a
humongous amount of files on their system, there should be lots of
space available on a 1TB drive for Windows and two or three other
systems. (After losing a slew of music downloads after a drive failure,
I no longer store anything like that only on a drive; I copy the files
to a CD. Unfortunately, all those downloads were from the
free system that is no longer available, and so most of the songs
aren't either.)

The beauty of using the name, Jessie, instead of Testing is that when 
Jessie becomes Stable, the system will automatically upgrade to 
Stable.  As soon as Jessie is Stable, the floodgates in Testing will 
open and all the new packages will just rush in.  By staying with the 
name Jessie, you can chose your moment to go back to Testing.

 Since the BIOS shows the full 16G, the problem doesn't seem to be on

POST displays a message on the screen that 16GB is present.  But that
subroutine is separate from the BIOS code that generates the e820 memory
map that is presented to the kernel, e.g.

BIOS-provided physical RAM map:
 BIOS-e820:  - 0009f000 (usable)
 BIOS-e820: 0009f000 - 000a (reserved)
 BIOS-e820: 000f - 0010 (reserved)
 BIOS-e820: 0010 - bddde000 (usable)
 BIOS-e820: bddde000 - bde0e000 (ACPI data)
 BIOS-e820: bde0e000 - d000 (reserved)
 BIOS-e820: fec0 - fee1 (reserved)
 BIOS-e820: ff80 - 0001 (reserved)
 BIOS-e820: 0001 - 00083efff000 (usable)

This is exactly what is happening in the OP's case--POST says one thing,
e820 another.

It is possible to manually create a proper map using kernel command line
options so the kernel sees all the memory.  However, for a non kernel
hacker this job will require far more time, research, etc, than the cost
of swapping modules.  Thus, if moving the DIMMs around doesn't allow the
BIOS to create the proper e820 map, the OP's best option is to buy
another matching 8GB stick, or swap it for two matching 4GB sticks.

Missing resolutions, xrandr and nvidia

[Alex Naysmith]

With Debian Wheezy installed, I have the Geforce 6800 GT graphics card. The
screen flickers every few seconds with the default nouveau drivers. I
therefore installed the version 304.88 nvidia drivers [1].

These drivers enable 3D acceleration as well as eliminate the screen
flickering. However, I have a limited range of screen resolutions available.

I know 1680x1050 60Hz is available on my HDTV. When I try to use xrandr to
add a new mode with the following commands..

xrandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053
1059 1089 -hsync +vsync

xrandr --addmode VGA-0 1680x1050_60.00

I get this error message:
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  154 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  29
  Current serial number in output stream:  30

This is apparently due to the incompatibilities between xrandr and the
nvidia compiled driver. Is anyone aware of a version of nvidia driver that
does work with the Geforce 6800 GT?

gcc and associated pkgs

equivalent versions of gcc, gcc-base, cpp? Anything else?

unstable and vbox additions

 I use zfs with debian wheezy, and am migrating to using zfs almost
exclusively for my local deployments.  The "kernel patches" are actually
just an add-on module that builds and installs from a repo maintained for
wheezy, which uses DKMS to manage the actual kernel module.

As for not working with 3.12,   that's a known issue, and a patch is in
head.  The ZFS team is closing a few more bugs and preparing a new release
of ZFS soon, which will build against 3.12.

There's currently discussion on one of the debian lists (I forget which)
about removing the possibility of having nearly-native zfs support in
debian-installer  I'm wasn't subscribed to the list at the time of the last
post to this thread, so I can't reply to it.  Unfortunately, due to the
nature of the CDDL (The license ZFS is under), No Linux distro will ever be
able to deploy native binary modules with the installer or in default
repositories any time soon.

ZFS is awesome, and I've never lost any data using ZFS, despite some bad
situations including marginal drives and even drive failure.  I highly
recommend this solution for everyone who's competent enough to understand
the procedures involved and the achievable benefits. Unfortunately, due to
the proprietary nature of the CDDL, I don't foresee this being a solution
"for the masses" any time soon.

Well, the choice of jessie or testing doesn't seem to explain the
trouble I was experiencing with the lack of updates.  Does anyone have
an idea of why I have to choose 'always prefer testing' rather that
'always prefer latest' in Synaptic preferences to get updates?  I am
also in testing on my old computer and do not need to do this.  I
guess if it works it works, so why worry.  It just makes me curious
what's making it do this.  BTW, I also use jessie in the sources.list
on the old computer for all the debian.org repositories.

Jon

Add a separate /home after installation?

[Jon N]

Hi,

When I installed Debian I put everything in one partition.  Now I'm
wondering what I was thinking.  / is ext4 for mated on a drive with
eufi partition table, no raid or lvm.  My thought is if I can shrink
that and create a new partition I can copy over /home and then mount
it as /home.

I am pretty sure it can be shrunk, although I guess I'll have boot
from another disk (it can't be shrunk while mounted I would guess).
Does this sound like a reasonable way to do this?

Thanks,
Jon

CDDL is FSF approved, so it is definitely a "Free-Software" (libre)
license. It's just that it's not GPL compatible, which is unfortunate,
but I wouldn't worry about that - just install ('auto build' or
whatever) the ZFS module.

If you don't do any compiling, why keep any of them? Of course, if you
do then only you know which ones you want.

I'd just purge the ones I don't want, and if another package depends on
it, I'd see if I want that one, if not purge it - repeat til satisfied.

Sure you can do that. e.g. boot from a Live CD like gparted and shrink
the slice, then create another slice in the remaining space.

Format it.

Mount the first slice (your root partition) with the Live CD and edit
/etc/fstab  e.g.:-
blkid >> $LiveCDmountPoint/etc/fstab
then edit fstab using the UUIDs that the last command appended to it
(don't forget to remove output of blkid from the bottom of fstab).

Now mv the existing home to the new slice.

Reboot into Debian on disk. Done.

Everything and the kitchen sink into a single slice works, but it's not
optimal. It's easier to hunt for a fish in ponds than it is in an ocean
- index are similar, so fsck times and the ability to easily back up
/home are not the only reason to separate / and /home. It also reduces
the extent of damage from operator error when modifying bulk files. In
most cases allocating more than 20GiB to /root is just wasted space -
especially as /home tends to be the biggest space using meta-directory.

Kind regards

Use "apt-cache policy" to see what are your repositories' priorities,

probably changes Default-Release in apt.conf[.d/], but, I don't
recommend it because I think it's simpler to specify everyting in

Debian freezes while booting

Hello Debian users,
I recently bought a gluglug X60s laptop and once received I installed
Debian on it (wheezy i386).

The installation was done using the netinstall CD; I only installed base system
plus laptop programs and apt-get install'd other stuff (xorg, alsa, etc.) later
on.

The problem is that more often than not, when I boot debian, after typing the
password for the encrypted volume, the boot process hangs (black-but-not-off
screen, unresponsive to key presses). I say more often than not because once
in, say, 20 boots everything goes smoothly (so I can login in a terminal,
start x, etc.).
I documented my actions during boot taking pictures [1] (resized them via
command line, I hope they are readable enough).

After browsing for solutions, I found that putting 'nomodeset' as a kernel
boot option allows me to reach login without any error. Unfortunately, after
logging in, I cannot 'startx' (error: no screens found,
I attach /var/log/Xorg.0.log).

I am puzzled about this and am not sure what to do next to diagnose the
problem. Any idea on how to address the matter is welcome! Thanks

nm-applet reports 802.11 connected, but can't actually communicate over network?

[Carl Fink]

I'm trying to use my Testing system with a Realtek rtl8188ce 802.11 adapter.
I use Gnome's nm-applet to connect to the wireless access point, and it
accepts the passphrase and connects, fine. However, all attempts to do
anything over the network fail, e.g. ping, traceroute, attempts to open a
web page all time out with no result.

My first thought was name resolution but I get the same thing with an IP
address.

My Windows 8.1 ultrabook connects to this network fine. So does my Android
phone. So does my (company-issue) iPad. Why is the Debian system failing?

I do have the Realtek nonfree firmware installed and this system worked OK
in another building using a different WiFi router.
