Richard, Merijn,

would switching to tmpfs be mandatory for everybody - or could
Merijin for his system opt-out of it?

Drop the second i, one will do :) Merijn, the salutation was ok

Looking at the discussion, might be worth to create a page with more
details on the implementation,

On btrfs: mksubvolume /tmp
On everything else: disable tmp.mount

In preparation on the upcoming changes as announced

* Change of /tmp to tmpfs

I checked

• Using btrfs? No
• Mounted? No

$ di /tmp/
Filesystem Mount Size Used Avail %Used fs Type
/dev/nvme0n1p6 / 220.7G 42.4G 178.3G 19% xfs

$ sudo systemctl disable tmp.mount
Unit /etc/systemd/system/tmp.mount is masked, ignoring.

Uh Oh, now I don't know what to do to prevent /tmp turning into tmpfs

This is always a one liner. So people who really don't want /tmp on
tmpfs can disable it easily during installation or afterwards with a
fresh installation. With btrfs in upgrade case, you have to edit /tmp
to enable /tmp on tmpfs. On other systems, disable tmp.mount.
That's all no big magic and no complex thing with many manual steps.
