bcachefs-tools/Makefile
Steinar H. Gunderson e9fec00f86 Make initramfs hook install mount.bcachefs 
Now that the bcachefs tool unconditionally includes the mount parts
(or more correctly, you cannot build it at all if you don't have Rust),
we can call copy_exec on mount.bcachefs, to get the symlink installed.
In particular, this helps with mounting UUID mounts as /.

See also https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1060411
for the remaining parts needed in initramfs-tools itself.
