There way well be. One possible scenario is installing Debian, then
installing again but overwriting the filesystems. To all intents
and purposes, the same responses will get you to the same place,
*but* the swap partition will have been recreated with a new UUID.
To avoid having the swap partition recreated is slightly tedious.
I do it as a matter of course because my swap is referenced by
LABEL rather than UUID. You have to force d-i to install without
one, and then enable it afterwards in VC2 (if you actually need it
for the d-i's use, which I don't) which is disapproved of.

Quite possibly. Do you need it, particularly on the desktop (which
I assume you don't hibernate). Maybe on the laptop.

Are you copying in a pre-existing /etc/fstab by any chance? Fine if
you use LABELs, but it needs checking/editing if you rely on UUIDs.
