Subject: [PATCH 1/2] Debian: ensure smooth upgrade paths when files are moved
 between packages

Upgrade path from bcachefs-tools 1.31.2 -> 1.31.5 is broken,
stuff was moved from -dkms package into main tools package,
and that famously does not work out of the box.

Ensure that any incompatible bcachefs-kernel-dkms package version
is truly marked as being replaced.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces
See https://wiki.debian.org/PackageTransition, case #10
