Comment 26 for bug 1824812

Ordering was important:

$ modprobe shiftfs
$ sudo snap set lxd shiftfs.enable=true
$ sudo systemctl restart snap.lxd.daemon
Now it is enabled:
$ lxc info | grep shiftfs
    shiftfs: "true"
$ lxc exec d-testapparmor -- mount | grep shift
/var/snap/lxd/common/lxd/storage-pools/default2/containers/d-testapparmor/rootfs on / type shiftfs (rw,relatime,passthrough=3)
/var/snap/lxd/common/lxd/storage-pools/default2/containers/d-testapparmor/rootfs on /snap type shiftfs (rw,relatime,passthrough=3)

And with that I can reproduce the bug:

$ lxc exec d-testapparmor -- aa-status
apparmor module is loaded.
0 profiles are loaded.
0 profiles are in enforce mode.
0 profiles are in complain mode.
0 processes have profiles defined.
0 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.
$ lxc exec d-testapparmor -- apparmor_parser -r /etc/apparmor.d/sbin.dhclient
AppArmor parser error for /etc/apparmor.d/sbin.dhclient in /etc/apparmor.d/tunables/home at line 25: Could not process include directory '/etc/apparmor.d/tunables/home.d' in 'tunables/home.d'
