given that the scope of systemd is not defined, how long for it to settle down? it could be a couple of decades.

Part of what people aren't liking is the dependence on linux-only features without any fallback to operate without them.

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. That would be one linux-only feature that would change from a hard dependency to a feature to be used when available.

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.
