Title:
cgroup lite postinst fails (init script doesn't start)
Status in “cgroup-lite” package in Ubuntu:
Fix Released
Status in “cgroup-lite” source package in Precise:
Fix Committed
Status in “cgroup-lite” source package in Quantal:
Fix Released
Bug description:
SRU Justification:
1. Impact: Customized installations which mount cgroups in nonstandard
locations may cause cgroup-lite to fail to start correctly
2. Development fix: have cgroup-lite do nothing if cgroups are found mounted
anywhere at all
3. Stable fix: same as development fix.
4. Test case:
Create an upstart job:
{{{
start on starting cgroup-lite
pre-start script
mkdir -p /mnt2
mount -t cgroup -o freezer freezer /mnt2
end script
}}}
reboot and check whether cgroup-lite is working. Manually try
{{{
stop cgroup-lite; start cgroup-lite
}}}
and check for errors
5. Regression potential: If a system has a mount with 'cgroup' in the
name which is not a cgroup mount, cgroup-lite will no longer mount cgroups.
Similar symptom to https://bugs.launchpad.net/ubuntu/+source/cgroup-

Hello Thomas, or anyone else affected, Accepted cgroup-lite into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/cgroup- lite/1.1.1 in a few hours and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

[Bug 985884] Re: cgroup lite postinst fails (init script doesn't start)
Thanks for reporting this bug. The start script does check for cgroups already being mounted in the standard locations, but your scripts install them in a non-standard location which cgroup-lite wasn't checking for. It should be fine to update the cgroup-lite upstart script to stop if cgroup shows up in /proc/mounts at all. That is probably the best fix. ** Changed in: cgroup-lite (Ubuntu) Importance: Undecided = High ** Changed in: cgroup-lite (Ubuntu) Assignee: (unassigned) = Serge Hallyn (serge-hallyn) ** Also affects: cgroup-lite (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: cgroup-lite (Ubuntu Quantal) Importance: High Assignee: Serge Hallyn (serge-hallyn) Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/985884 Title: cgroup lite postinst fails (init script doesn't start) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgroup-lite/+bug/985884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 985884] Re: cgroup lite postinst fails (init script doesn't start)
Ah yes. We do have something that has already mounted them. So it seems that the start script should make sure things are mounted properly, but not fail because they are already mounted...unless it's in the wrong place, or in a conflicting manner. I don't think that's the case here, however.

Still, package installation should never fail for such a reason; this is a general problem with reflecting errors in unit scripts back to postinst. Well in the common case, packages that are expected to start a service at install time need to report such errors so that dependent packages don't fail with even more obscure errors. I don't know if that's appropriate here or if we should indeed just be ignoring all errors from this job on package install. Was a /var/log/upstart/cgroup-lite.log file created? Could you post its contents? It's possible the mount operation succeeded but the job failed for some other reason. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/985884 Title: cgroup lite postinst fails (init script doesn't start) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgroup-lite/+bug/985884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
