The Grumpy Editor's guide to surviving the systemd debate

> If cgroups are required to be in the kernel, but you can operate without using any controllers (as was stated in some thread on lwn in the last few days), then refusing to boot when cgroups aren't in the kernel is the wrong thing to do.
Uhm, you still NEED cgroups to use systemd. It can't really work without them.

However, you don't need any cgroups-based resource management to be turned on (or even compiled in). In this case cgroups will be used only for process tracking and nothing else.
