> * Stop installing tmp.mount by default; there are still situations where it
becomes active through dependencies from other units, which is surprising,
hides existing data in /tmp during runtime, and it isn't safe to have a
tmpfs /tmp on every install scenario. (Closes: #783509)
- d/rules: Ship tmp.mount in /usr/share/systemd/ instead of
/lib/systemd/systemd.
- systemd.postinst: When tmp.mount already was enabled, install tmp.mount
into /etc and keep it enabled.
- systemd.postinst: When enabling tmp.mount because of RAMTMP=yes, copy it
