Does someone have a working tmp on tmpfs via

# 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:
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.
