I apologise if this is not the appropriate list for the following

Is it possible to upgrade the Linux kernel on a kickstart CD?

I've changed the vmlinuz and initrd.img files in the isolinux
directory from the distro's ISO image; so kernel
2.6.32-504.3.3.el6.i686 now boots from a DVD, and loads the
appropriate modules and firmware from the stage 1 initrd.img.

However, anaconda (13.21.229) exits abnormally with a DBusException
(org.freedesktop.DBus.Error.NoReply); possibly because NetworkManager
is unable to launch the wpa_supplicant.

Anaconda appears to be choking during initialisation:

anaconda.id = instClass.installDataClass(anaconda, extraModules,
opts.display_mode, anaconda.backend)

install exited abnormally [1/1]
The system will be rebooted when you press Ctrl-C or Ctrl-Alt-Delete.

The shell prompt is available on tty2; and so I can see the syslog,
which has repeated messages at its tail end:

INFO NetworkManager:  Trying to start the supplicant

So, something needs to be changed somewhere (kernel recompilation?
missing module? wpa_supplicant / NM upgrade? stage 2 install.img?)
which is where I'm stuck. Do I need to hack Wifi NIC related lines out
of anaconda?

The reason that I'd like the final kernel version to be running during
the install, is that it's needed to compile the low-level driver for a
FIPS-140 crypto coprocessor. The target system will be an off-line
certification authority system, and will certainly not need Wifi (in
fact the hardening procedure foresees removal of most network hardware
drivers).

I know I could do everything in three stages (initial install -
software upgrade - crypto driver install); but being able to do
everything in one go would simplify business continuity / bare metal
recovery.

In the meantime, I'm very happy to have learned something about
anaconda / kickstart and so on, which will be very useful in future.

If there's a quick fix to the above issues, I'd be happy to hear it.

Thanks in advance

Sounds like the "Rolling media" announced in:

http://lists.centos.org/pipermail/centos-announce/2014-December/020807.html

could be useful to you, although judging by the kernel version you
mentioned, it looks like you're looking for CentOS 6 updates.
Unfortunately, it appears the rolling media is only available for CentOS
7 at the moment.

Did you update modules.dep and modules.alias in the stage1 image?

Thanks Greg,

I think so: I used depmod in the attached bash script 
(update_initrd.sh); on my system, the command expands to:


/sbin/depmod -b /tmp/initrd -F 
/tmp/root/boot/System-map-2.6.32-504.3.3.el6.i686 2.6.32-504.3.3.el6.i686


where /tmp/initrd is the working directory for preparing the initrd file 
system; /tmp/root is where the kernel and kernel-firmware packages have 
been extracted.


The script is my attempt at copying only the kernel modules already 
present in the original initrd. It also looks for RPMs required by the 
latest kernel version (it identified kernel-firmware, initscripts and 
iproute), and copies changed executables (only the ip command).


Thankyou for suggesting the Rolling media; I'll take a look at that.

I'm using CentOS 6 because I based my hardening process on the DISA STIG 
for RHEL6; I haven't checked to see if there is now an equivalent for 
CentOS 7.

Re: [CentOS] Design changes are done in Fedora

[Elvinas Piliponis]

Hello,

Kt, 2015 01 08 11:32 -0600, Valeri Galtsev rašė:


right: "snorkel" ;-) One of the pushing points was: already then on
average every 30-45 days was either glibc or kernel update, meaning you
have to reboot the box (and on multiple threads here there was a bunch of
other unpleasant things mentioned so I'll skip them...). Linux from


And your point? From my previous Linux Engineer experience in some
small enterprise, being one of the top 5 biggest banks, there was a
push to make mandatory scheduled server reboots every month or two.

Rationale was simple: keeping long uptimes does not makes sense, when
updates (not necessary OS but also userspace) piles up and after
unexpected reboot shit happens as server is no longer able to boot.
This was the experiences with various systems, including RHEL5 on x86
and IBM AIX on Power, Windows and other lovely bunch of hardware. As
there were multiple incidents, it was decided to move to a mandatory
reboot schedule to have maintenance windows. I believe the only system
that was excluded from such plans was mainframe.

Of course this requires to design systems to have load balancing,
failover and other stuff available and working.



So, several of those people fled to open solaris. My journey was
different, I ended up migrating a bunch of most important boxes to
FreeBSD. I know how many on this list are already allergic to me saying
this, I promise, this is the last time. I'm using as excuse something
familiar I feel in James's post...



And does FreeBSD have magic bullet against reboot requirement after
kernel/libc update? Or are you simply not patching system (which you
can do on Linux too) ?

BTW Linux already (again) procedes to rebootless kernel upgrade.
Unfortunately now there are 4 different implementations (thanks goes to
Oracle for buying KSplice and making this exclusive to OL). Although if
my memory does not fail there were talks about unification.

No, the elrepo packages are kABI-tracking kmod packages that are
compatible with the RHEL kernels stable ABI. These drivers work across
all RHEL kernel releases, no rebuilding takes place. This is unique to
Enterprise Linux (RHEL and it's clones) and different to how things may
happen on other distros or when using the NVIDIA installer.

Your card is supported by the latest elrepo driver release, so just make
sure you are yum updated to the latest release (currently
kmod-nvidia-340-65):

yum --enablerepo=elrepo update kmod-nvidia

Reboot if the driver gets updated and you should be good to go.

[CentOS] C-6, Gnome question

[Fred Smith]

Hi all!

Using the default Gnome desktop on Centos-6, I keep having difficulty
getting the mouse pointer to lineup exactly on the edge/corner of a
window when I want to resize the window. It seems that you have to 
have it on a line exactly one pixel in width, and I'm finding it
increasingly hard to do (who, me? getting old? nah!)

Wondering if there is a gnome setting somewhere among the myriad
settings that could be used to configure the accuracy with which
the mouse pointer must be placed so one can grab edges of things.
I've dug thru the settings in the Gnome configuration editor, but
so far nothing leaps out at me.

Can anyone offer advice?

thanks!

[CentOS] Camera doesn't works after "yum upgrade"

[Patrick Begou]

Hi,

I've launched  a "yum upgrade" command on a CentOS6 laptop which has updated 
nearly 600 packages. Automatic updates were not working because of a conflict on 
a package.


So the laptop is now uptodate but the camera did not works after this. The 
message is:


kernel: uvcvideo: Failed to query (GET_DEF) UVC control 6 on unit 2: -110 (exp. 
2).

The camera is detected as USB, lsusb shows:
Bus 001 Device 003: ID 0c45:646b Microdia

I've tryed to boot on alternative kernels but no change:
- vmlinuz-2.6.32-504.3.3.el6.centos.plus.x86_64 (which solve a camera problem on 
my laptop)

- vmlinuz-2.6.32-431.29.2.el6.x86_64
- vmlinuz-3.10.63-1.el6.elrepo.x86_64

Any idea about a faulty package ?
I've added the upgrade log in attachment but it's quite big. The first four 
erased item were because of conflicts. Some are re-installed after the upgrade 
(end of the log file)


Thanks

Patrick

I am a bit confused. Was the camera problem solved with the centosplus
kernel? Or are you referring to yet another camera problem? If the
former, this is a known issue:

It was a previous problem on my personal laptop.
The current problem is for the laptop of a student and changing the kernel 
doesn't solve it.

Thanks Marc for your answer, I have a /dev/video0 but no /dev/video.
Should I create a link ?
Or a new rule in udev ?

We use motion, so I' m not familiar with camera, but does it load an v4l2

Have you gone into System->Preferences->Mouse and changed some of the
doohickeys there? I don't recall anything related to your problem, but
it may be related to Acceleration or Sensitivity? I've set my
Sensitivity to about 1/3rd off of low and acceleration to mid-range.
There's an alternative if, like me, you prefer KB anyway - -.
It's drawback is it's not as fine-grained though. But for me it's really
faster anyway.

Bill:

Thanks for the reply.

I've got acceleration all the way to the slow end, sensitivity all the way
to the low end, drag and drop threshold all the way to the small end,
and I've tried them all at other settings, too, to no avail.

trying to grab the edge of a window feels like the grabbable region
is only one pixel (or maybe one "mickey") wide and it's still hard nto
place the pointer right on it. I may be getting old, but I don't
have any palsy/tremor problems.

Is change for advantage and betterment or merely because someone wants
to do the same tasks in a different manner and wants everyone else to
abandon their existing methods of working ?

Changes are not inherently bad but changes prompted by others' amusement
are usually unproductively disruptive.

Enterprise, in the RHEL context, suggests stability or have I

The one east of the Atlantic continues to decline and is only "great"
when compared in size to Brittany in the north-west of La France. 

Great Britain actually means a Brittany bigger than the French area
called Bretagne.

The USA has certainly damaged my language. These days (ever since George
W) one no longer devises a "plan". Instead one makes a "road map" :-)

Adapt sounds more pleasant than "disruptive change". It suggests a less

Well, that's the limit of my offerings. I'm still trying to find the
thing I used back in C5(?) that raised the panels when the mouse hovered
over it for X seconds. With C6 I can't find it anymore and it switches
way too fast.

I recall some folks mentioning something like "gnome-config" or similar
and I figure that'll be my next attempt. I looked to see if there was
anything in the drop-downs from "System" to see if anything else jumped
out. I didn't see anything about border widths. There's a "Desktop
Effects" that I don't know if that has any effect on your problem:
System->Preferences->Desktop Effects. Has some text in it about 3D
hardware acelleration.

You know wht? I'm thinking it's something to do with the mouse driver.
Usb mouse? ISTR some "jerkiness" in that human interface stuff in the
past.

One other (likely?) difference that may be making my unit better
behaved. I have gpm installed so that I can C&P on text-based standard
terminals (console tty). I've noticed that when X or Gnome starts up it
seems aware.

You might want to try installing gpm, have it start up on boot and see
if that helps. Not a true solution, but may be a work around until the
true solution is found.

HTH,
Bill

Have you tried different window manager themes? Some of them have larger

in C6  it's in SYSTEM | PREFERENCES | WINDOWS
there's a slider titled "interval before raising".

Which makes me wonder how one modifies a theme... there must be a
special toolkit for it somewhere... ??

I presume you're talking about panels with "Autohide" set. If you have
the GUI gconf-editor installed, it's under apps/panel/global/panel_show_delay.
You can also set it from the command line:

gconftool-2 --type int --set /apps/panel/global/panel_show_delay 500

(The default is 300, unit is milliseconds).

If you roll back all the changes made to English since colonial times, you’re 
left with Middle English.  So, how do you feel about Chaucer?

Those who try to fight the inevitable changes that language goes through end up 
as laughing stocks:

It’s a bit of a glib observation, but there’s a serious core to it.

Pencils, paper, carpet, and toasters were once technology.  They were luxury 
items, manufactured by skilled artisans.  Now they come off an assembly line, 
durable and perfect, every time.

The original sense of the word “technology” comes from its Greek roots, meaning 
a treatise on some art, such as a book on how to brew beer.  We don’t use the 
word that way any more.  In the 1970s, we started to distinguish some 
technology as “high” technology, then high-tech, and now just tech.

I’m not really serious about this new definition for technology, but it is a 
useful one.  It is entirely within the normal scope of language evolution for 
it to become the new sense of the word.
