A bug has been opened for this problem https://bugs.gentoo.org/828963.
It suggested emerging with --backtrack=200. That solved the problem for
me.

It very much does matter whether you use a swap file or partition in 
practice. I've just been reading right now a discussion about systemd 
logging and hibernation, and how btrfs handles swap files. It sounds 
nasty.


If you have a swap file, linux creates an immutable file then uses 
direct disk i/o. There's a LOT of unnecessary crap there that could 
go wrong. Just avoid all that trouble and give yourself a decent swap 
partition. (And if you're running btrfs, a lot of this sounds 
experimental and dangerous ...)


Cheers,
Wol




For BTRFS I usually do one partition for the whole system and one
partition for swap and then use subvolumes for /home and anything else
I want to keep separate in case of reinstall.

Since BTRFS is a storage pool model, everything else can dynamically
resize similarly to using LVM.

Swap files in general aren't as reliable if one is planning to
hibernate the system.  Swap files on BTRFS should go through a loop
device unless you set them up really carefully.

There's no reason you can't have both swap files and a swap partition.
 I occasionally end up dynamically adding more when I get a program
that uses a terabyte of virtual but very little resident at a time or
something.

Swap onto zram devices can also be a useful tool if the data being
swapped is more highly compressible than zswap will take advantage of.

Thanks to all for hints. I've created a swap partition.

[gentoo-user] Local mail delivery agent (MDA) wanted

[Frank Steinmetzger]

Hey list,

I am looking for an as-simple-as-possible setup for local mail delivery.
What I mean by that is: the mail shall go into /var/spool/mail locally,
which is why I deem it overkill to set up and run a complicated smtpd
daemon with its own config file language.

At my previous employer we used mda on our Ubuntu-based machines, but this
is not available in Gentoo. It did extactly what I am looking for: receive
mail (most importantly from cron) via pipe and put it right into the spool
file, so I can see a message upon login and read it with mutt. That’s all
I need, so I can get summary reports of zfs snapshots, smartd messages and
so on.

I was looking through wiki articles, but they all employ the usual beasts
postfix, courier and so on. Do you have any recommendations?

Much obliged.

I have never used mailutils mda; I just noticed that there is a
configuration option
--disable-build-mda for mailutils [1] and thought, maybe, adding
$(use_enable build-mda) \
to the mailutils ebuild [2] will help to get mda in Gentoo.

Revdep-rebuild won't work because vmware-workstation is a binary package.
You may need to add a file to /etc/revdep-rebuild that adds the vmware
path (somewhere in /opt?) to SEARCH_DIRS_MASK.

It means the binary wants to load some libraries (like libexpat.so)
portage can't find.

> (And before anyone asks, the software works just fine, and neither 
> revdep-rebuild nor revdep-rebuild.sh find anything wrong.)

But vmware (or rather, the linker) seems to find them. Maybe they are in
the same directory as the binary and portage doesn't search there? You
can check which libraries exactly the binary wants to load with ldd.

[gentoo-user] Bug in run-crons?

[Frank Steinmetzger]

Hi, it’s me again, :)

I’m currently improving the cron setup on my Gentoo-powered NAS. I installed
zfs-auto-snapshot, which includes scripts for hourly, daily, weekly and
monthly creation of snapshots.

The NAS uses fcron for its cron daemon. In order for the scripts to work,
I enabled the run-crons script from sys-process/cronbase, which runs all
scripts in /etc/cron.{hourly,daily,...}. But I have the feeling that there
is a bug in the script:

It uses state files in /var/spool/cron/lastrun/ to know when each interval
was last run, so it only runs once per period. But: the age threshold for
the state file is period + 5 minutes. Shouldn’t that be period - 5 minutes?

My reasoning: assume run-crons is run hourly, at the 0 minute sharp. So at
the next run, the state file is exactly one hour old. Since this is not old
enough for the check, run-crons thinks that the last run is too recent and
ignores this period. As a result, each period is only run on every other
iteration.

Any thoughts on that?
Cheerio.

I don't use this, but I believe there should be an hourly crontab
entry that deletes the cron.hourly file, which would mean it gets run
on the next 10min cycle (or maybe sooner - I'm not sure if those jobs
are run in parallel or serial).

The overall result is that things will get run at traditional crontab
times no matter what, but if those are missed and enough time is
accrued then run-crons will catch this and run the job on the next
10min cycle, such as a missed daily overnight slot.

So if you don't have your computer on a 3AM then the job will get run
a bit more than 24h after the last time it was run.  Then if you leave
it on overnight that night it will run at 3AM despite it not being
24h, but at that point if you leave it on it will run at 3AM daily
since it will no longer be missed.  The fixed times serve to anchor
the actual execution times if you do leave the computer on.

The check that I mentioned above is actually the deletion which you mention:
run-crons looks for the state file for the given interval and - if it is old
enough - deletes it.

The part that executes the individual cron scripts is only executed if there
is no state file. The first thing it then does is to create a new state file.


In pseudo code:
1. look for period state file that is older than interval + 5 mins
found one?
delete it

2. Look for period state file
none found?
create state file
execute cron scripts for that interval

You can actually just use

$moduleDir/bin/python -m $module

Executing anything from the bin directory inside the venv will make it act
