Red Hat Bugzilla – Bug 606854
FHS violation
Last modified: 2010-09-10 23:35:18 EDT
Description of problem: libcgroup ships a directory /cgroup This violates the FHS. Version-Release number of selected component (if applicable): libcgroup-0.35.1-1.fc13.x86_64 Expected results: This directory must be removed or located somewhere else.
Define somewhere else? There is no consensus about where it should be located, and /cgroup is as good a location as some other.
(In reply to comment #1) > Define somewhere else? What is this directory supposed to contain? > There is no consensus about where it should be located, and /cgroup is as good > a location as some other. It is not. What you did is a very ugly "MUST NOT HAVE HAPPENED". The fact his package made it into Fedora is evidence that this package wasn't carefully reviewed, and made it to sneak through the _wide_ cracks of QA.

Let me clarify where /cgroup comes from libcgroup allows users to create /etc/cgconfig.conf and that file specifies where cgroups should be mounted. We discussed this at length on the mailing lists, including lkml. Fedora defaulted to /cgroup for this location (jsafrane, please correct me if I got the history wrong). Other options were /sys/cgroup and /dev/cgroup. This directory is not created at install time, but at run time and then cleaned up when the service goes down. This can be easily fixed up without impacting any user (AFAIK), but please tell us what FHS recommends as the location to mount a pseudo filesystem.
