I thought some distro may still only support V1. I do my most work on Ubuntu22.04 which by default is v1 so it's convenient for me to test. But not strong opinions.+CG_ROOT=/sys/fs/cgroup
+if [ ! -d "/sys/fs/cgroup/misc" ]; then
+ echo "# cgroup V2 is in use."
+else
+ echo "# cgroup V1 is in use."
+ CG_ROOT=/sys/fs/cgroup/misc
+fi
Does the test need to support v1 cgroups?
