Hi,

could you please show a simple script (doing lxc-create && lxc-start &&
lxc-wait && lxc-attach) that I could reproduce with?

Just to be sure - you get this error running this by hand, right?  If it
happens at boot time, then you should make sure that the 'lxc' init job
has completed before your job begins, since that is the one which will
load the apparmor profiles.

Title:
  failed to change apparmor profile to lxc-container-default-with-
  nesting

Status in lxc package in Ubuntu:
  Incomplete

Bug description:
  I develop and maintain the unity8-lxc package (lp:unity8-preview-lxc)
  which uses an unpacked Ubuntu Next Desktop ISO as a privileged rootfs.
  It uses the lxc-container-default-with-nesting apparmor profile since
  we'd like to support containers within this.

  When I try to do a lxc-start. lxc-wait(RUNNING), and lxc-attach for
  the first time in my setup script, I get the following error:

  lxc_container: lsm/apparmor.c: apparmor_process_label_set: 183 No such
  file or directory - failed to change apparmor profile to lxc-
  container-default-with-nesting

  I believe this is a race because if I introduce a sleep of say 0.5
  seconds between the lxc-wait and lxc-attach, then it works.  It also
  works for any subsequent lxc-start/lxc-wait/lxc-attach after this
  failure.

  Please let me know if I can provide more info.
