I get the error mentioned also here: The /cgroup filesystem is not mounted [#33830] | Virtualmin
Failed to save LXC host : The selected system cannot support LXC containers : The cgroup filesystem is not mounted

lxc is installed and lxc-checkconfig gives

LXC version 5.0.2

SYSTEM INFORMATION
OS type and version Debian 12
Webmin version 2.105

To set it simply, can i set cloudmin to use cgroup v2? or should i enable cgroup v1 on systemd?
