Comment 6 for bug 1390223

I went ahead and upgraded to vivid. My kerberos/ldap problems are solved but I still get:

$ mailq
postqueue: warning: close: Permission denied

guest is trusty:

ii postfix 2.11.0-1ubuntu1 amd64 High-performance mail transport agent

host is vivid:

ii lxc 1.1.0-0ubuntu1 amd64 Linux Containers userspace tools
ii apparmor 2.9.1-0ubuntu7 amd64 User-space parser utility for AppArmor

Linux venkman 3.19.0-9-generic #9-Ubuntu SMP Wed Mar 11 17:50:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

As #2, I get "Permission denied" ~997/1000 tries (in a loop).

ubuntu@test:~$ for i in {1..1000}; do mailq; done 2>&1 | grep -v Permission
