Does someone have a working tmp on tmpfs via

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

- do not mount /tmp as tmpfs (#1578772)
- Enable /var/run and /var/lock on tmpfs
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.
