Public bug reported:

The pivot_root apparmor regression test fails when systemd is the init
daemon:

running pivot_root
Error: pivot_root failed. Test 'PIVOT_ROOT (unconfined)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (bare rule)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (new_root)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (put_old)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (put_old, new_root)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (transition)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (new_root, transition)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'
Error: pivot_root failed. Test 'PIVOT_ROOT (put_old, new_root, transition)' was expected to 'pass'. Reason for failure 'FAIL - pivot_root: Invalid argument'

The reason for this is that systemd mounts the rootfs shared, which
prevents the pivot_root(2) call from succeeding. See the systemd commit
http://cgit.freedesktop.org/systemd/systemd/commit/?id=b3ac5f8cb98757416d8660023d6564a7c411f0a0
for the justification why they do this.
