As mentioned, the way to control it will depend on the specific tool
used to mount.  E.g. if it's mounted by hand via a rule in /etc/fstab,
then you can rules that specify the device via /etc/disk/by-uuid.

Do note that partition UUIDs are not designed to be reliable w.r.t
malicious uses (it's easy to create a partition with the same UUID as
some other).

/dev/disk/by-id/ should be device specific.

Shoot, I had forgotten about WWNs at all! Yep, those should be good enough for my purposes.

Thanks for the hint!
