4. hostnamectl status hangs indefinitely
On the host, there are some audit messages for each invocation of
hostnamectl
[411617.032274] audit: type=1400 audit(1461695563.731:100):
apparmor="DENIED" operation="file_lock" profile="lxd-x1_</var/lib/lxd>"
pid=17100 comm="(ostnamed)" family="unix" sock_type="dgram" protocol=0
addr=none
It's related to socket activation. One can workaround this by running
systemd-hostnamed in the background first
root@x1:~# /lib/systemd/systemd-hostnamed &
[1] 2462
root@x1:~# hostnamectl status
