Bug Description
Almost half of the ubuntu_
e.g.
mount: /dev/cgroup: ltp_cgroup already mounted or mount point busy.
cgroup_
From investigation it seems there could be an issue with the transition to cgroup-v2. There have been rumors on the ltp mailing list that one of these days the tests could break due to the transition. Switching to cgroup-v2, likely due to a systemd update, could cause these tests to break due to different mount and cgroup hierarchy semantics.
I could only reproduce a subset of the new failures we are seeing, but after setting systemd.
