--- Comment #1 from Lennart Poettering <lennart at poettering.net> ---
systemd manages the cgroup hierarchy and moves processes around in it, that is
expected.

The only places where it's OK to manipulate the tree directly is:

a) when you run in a service or scope with Delegate=yes

b) on controller hierarchies systemd doesn't manager

c) when you stick to changing attributes systemd doesn't support natively, but
don't touch the hiearchy or process assignemnts.

Other than that the cgroup tree is a single-writer hierarchy. if you modify it
overriding what systemd does you are on your own
