I assume that bin/unity8-lxc-compositor is the script you are using.  But
how does it get run?  Do I just install that package in a container to
reproduce this?

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.
