I this on cgroupsv1?

We simply don't support the freezer on cgroupsv1, it's just too messy
of an interface.

It's supported fine on cgroupsv2 with a recent systemd version, where
you'll have "systemctl freeze", and things should just work.

[systemd-devel] Running containers under freezer

2021-04-02 Thread Bhasker C V 
Hi,
 Please could someone help ?

 I want my containers to run inside a freezer cgroup so that I can freeze
and thaw the container as and when needed.

 I use the command

 systemd-nspawn [...] --slice=bhasker.slice
and systemd creates
bhasker.slice and puts everything under it. The slice however is for memory
only.
I dont seem to be able to specify successfully how to use freezer in the
slice

If I do specify --slice=memory,freezer:bhasker  I end up getting something
like this

Control group /:
-.slice
├─memory\x2cfreezer:bhasker.slice
...

(the coma is taken literally as \x2c)
How do I get systemd-nspawn to also run the slice under freezer controller
of my choice ?
Thanks in advance
