If I understand things correctly "m" only works on already existing directories
and files, which means system.journal is already there with the wrong usr:grp,
and changing the owner of a sticky directory won't change the owner of the files
it contains... unless you do a recursive chown/chmod, which, I just noticed,
is what systemd does since commit a606871da50 (it uses "Z" instead of "m").

I'm gonna try that and report back.
