Title:
  Can't upgrade procps in LXC 1.1

Bug description:
  == SRU ==
  Rationale:
   sysctl now fails with current LXC as files which shouldn't be written to in containers are read-only. A previous fix applied to the EACCESS case as returned by apparmor.

  Text case:
   start procps

  Regression potential:
   All EROFS write failures will now be ignored (an error is still logged) but I can't think of a case where that'd be a bad thing. 

  Original bug report:

  LXC 1.1 on vivid has started giving privileged containers a read-only
  /sys, which prevents Ubuntu's procps Upstart job from starting. This
  isn't normally too problematic, except that the weekend's procps SRU's
  postinst tries to start the job and causes the upgrade to fail.

  Disabling the procps postinst makes apt usable again.
