you are either in legacy or hybrid mode. To distinguish these two cases, run
`statfs()` again on `/sys/fs/cgroup/unified/`. If that succeeds and reports
`CGROUP2_SUPER_MAGIC` you are in hybrid mode, otherwise not.

hierarchy (in unified and hybrid mode) as well as on systemd's own private
hierarchy (in legacy and hybrid mode). It won't pass ownership of the legacy

in cgroup v1 (as a limitation of the kernel), hence systemd won't facilitate
access to it.
Let's stress one thing: delegation is available on scope and service units
only. It's expressly not available on slice units. Why? Because slice units are

to them. If we'd allow delegation on slice units then this would mean that
both systemd and your own manager would create/delete cgroups below the slice
unit and that conflicts with the single-writer rule.
