[Bug 874989] Re: cgroup mount point in fstab causes boot process to hang

[Steve Langasek]

I've tested using the fstab entry from comment #3 and cannot reproduce
this issue in precise.  This is with the cgroup-lite package installed,
and cgroup still gets mounted on /var/cgroup.  Do you have a large
number of other filesystems listed in your /etc/fstab?  Perhaps this is
a race condition.

Title:
  cgroup mount point in fstab causes boot process to hang

Status in “mountall” package in Ubuntu:
  Incomplete

Bug description:
  I did a release-upgrade from 11.04 to 11.10 and noticed boot process
  hanging at 'init: Handling mount event'. I didn't wait for more than 5
  minutes to see if it ever proceeded from there. As a temporary
  solution, I went into recovery mode, selected the remount option and
  resume normal boot. Eventually I just tried removing the cgroup mount
  point ( cgroup          /cgroup         cgroup  defaults        0
  0 ) from fstab, did a normal mode boot, and it works.

  The behavior is reproducible. Just add a cgroup mountpoint in fstab
  and try booting.
