Well, but how can i get my service cgroup from outside systemd code, in bash
for example?
I previously used:
stat /sys/fs/cgroup/systemd/$(systemctl --user show -p ControlGroup
tmux.service|sed 's/.*=//' )
but it doesn't work when service is running in container via nspawn service
(systemctl start systemd-nspawn at grey.service)

Right now only way how i can get it is:
stat /sys/fs/cgroup/systemd/$(systemctl --user show -p ControlGroup
tmux.service|sed 's/.*=//' | sed 's/x5c//' )
