Does someone have a working tmp on tmpfs via
systemctl enable tmp.mount
under CentOS8/RHEL8? This seems to work straight in EL7 ...
# LANG=C systemctl enable tmp.mount
The unit files have no installation config (WantedBy, RequiredBy,
Also, Alias
settings in the [Install] section, and DefaultInstance for template
units).
Looks like a known issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1667065
It works in EL7 and F30. In EL8 it seems to be intentional :
$ rpm -q --changelog systemd |grep tmp.mount
- unit: don't add Requires for tmp.mount (#1619292)
$ grep -E 'tmpfs|tmp.mount' systemd.spec |grep -v devpts

The "remove" stanza leads to the missing "WantedBy".
Unfortunately all bz# are private ... so why they remove this
functionality? We then at least known what impact it has when
enabled.
I'm not quite sure why you don't appear to have read the bug I pointed
to. It has been fix in git (c8-beta branch) and will either be out with
8.1 or with an errata earlier if it is judged to be worth it.
Recognition is stronger then recall :-). There was no direct c8-beta
evidence and I was not aware of RH's public systemd branch, but I see
it now. For the archives:
