anon-software 04c8ae9a57 More flexible cgroup settings (#352)
* More flexible cgroup settings

If there are already required cgroup boot parameters present but in a
different order than specified, the script will add them again. It is
better to test for the individual parameter in a loop and selectively
add them as necessary.
