Yes, Condor is functional without cgroups. It just can't use cgroups
anymore. I'll drop this dependency temporarily, and reenable it whenever
the dust has settled.

If you can offer a list of things that need to be done in order to get
cgroups back into wheezy, I might be able to identify some aspects that
I could help with -- even without any practical cgroups experience so
far.

Plans to (re-)include cgroups in wheezy?

2012-04-26 Thread Michael Hanke
Hi,

I'm trying to get Condor [0] included into wheezy. I just now realized
that the cgroups package [1] which condor currently depends on is in a
rather bad shape (numerous bugs, only little maintainer response, last
upload a year ago, one upstream release behind).

Looking at HOWTOs like [2] it seems that the overall setup of cgroups in
Debian is suboptimal -- but I'm not really in the position to judge, as
I have no personal experience with cgroups.

However, I'd like to know if there is anybody (maintainer CC'ed) working
on getting cgroups in shape and have it in wheezy (Squeeze came with
cgroups support BTW).  If there is not such effort, I'll probably
disable Condor's cgroups features for now, as it would take me too long
to get up to speed with cgroups before the upcoming freeze.


Cheers,
Michael

Setup should (?) probably be handled by initscripts.  See
#601757.  However, we should also copy the set of mounts used
by systemd (?).

Is the proposed patch in this bug sufficient?  I've not yet looked to
see--I'm not familiar with cgroups, and I don't know if it's
sufficiently compatible with the systemd mounts.

Roger

You raise a good point, I am currently working on this package and I would love
to see it included in Wheezy if possible.  The new upstream release is actually
worse for me than the previous version, so I have quite a bit to do in order to
get things into shape.

If Condor is still reasonably usable without support for cgroups via libcgroup,
I would go that route -- at least in the short term.  Several of libcgroup's
problems are fairly complex, I'm doing all that I can given the time that I have
to get things sorted.  If anyone has input or would like to contribute, please
