Comment 17 for bug 1837227

I've successfully confirmed that the mount issues seem to be fixed using systemd from focal-proposed. Using the 'rep-tmpfs.sh' script, all variants ran without any issues for multiple rounds. Basic testing on a VM also looks good. Below are the versions used for this test:

$ dpkg -l systemd
...
||/ Name Version Architecture Description
+++-==============-=================-============-=================================
ii systemd 245.4-4ubuntu3.23 amd64 system and service manager

$ uname -rv
5.4.0-169-generic #187-Ubuntu SMP Thu Nov 23 14:52:28 UTC 2023

I'll look into the reported regressions next, to confirm none of them are caused by this LP.
