That is exactly the reason why /home is in a separate subvolume (and
also why there are so many subvolumes for various directories).

Btrfs snapshots are done on a per-subvolume-basis. So if you do a
snapshot of /, /home, being on a separate subvolume, is not affected.
Same with undo - if you undo a change on /, /home is not affected
because it is on a separate subvolume.

The snapper configuration in /etc/snapper/configs/root is only for / -
as long as you do not create a separate configs for /home or other
subvolumes, no snapshots will be created by default.

You can of course always put /tmp and /home on entirely different file
systems during the installation, that is up to you. And as Torsten
mentioned, indeed /home is put on XFS by default if there is enough
disk space.

Kind regards,

Björn
