I've added local dir (lxc config device add) to running (unprvileged,
default profile) containter and it just works, but after container stop, it
cannot start again with "Permission denied - Failed to mount". Any fix?
$ lxc start pld
lxc 20160926115846.879 ERROR lxc_utils - utils.c:safe_mount:1692 -

Local dir exists and has been mounted by lxd under /var/lib/lxd:
$ ls -ld /var/lib/lxd/devices/pld/disk.var-host
