The 'cgconfig' tool from libcgroup (http://libcg.sourceforge.net) can be used
to mount one or more instances of the cgroup virtual filesystem, instead of
using the 'mount' command. However, cgconfig does not update /etc/mtab,
although the mounted cgroup filesystems do appear in /proc/mounts. (I am using
Fedora 13.)
Since lxc commands such as 'lxc-execute' just search /etc/mtab to see if any
cgroup filesystem is mounted, this causes them to fail with "cgroup is not
mounted", even though this is not the case.
It seems to me that either:
1) cgconfig should update /etc/mtab, or
2) lxc should search /proc/mounts instead of /etc/mtab
(change one line in src/lxc/cgroup.c)
Which is the correct solution?
Thanks,
David
