That might not be an option for some: I'm still installing Debian on a
machine with only 512MB RAM.
But there is a smooth path for coping with the current situation
where you need swap and it's on an MBR disk:
1) use LABEL in /etc/fstab to specify swap partition(s) on
current systems.
2) allow debian-installer to reformat swap, giving it a
fresh UUID and a blank LABEL.
3) Any time during the rest of the installation process,
and at least before it finishes, restore the LABEL
to the swap partition(s):
a) open a shell on VC2 or VC3
b) # /target/sbin/swaplabel -L <your-label> /dev/sd<device>
4) Job done.
I don't use hibernation but AIUI the problems in the format of
RESUME=LABEL=… have been fixed (#861057) so the same should apply.
Of course, smoother still would be if the debian-installer would
offer a screen like:
┌────────────────────────┤ [!!] Partition disks ├────────────────────────┐

└────────────────────────────────────────────────────────────────────────┘
where you could specify the LABEL.
Cheers,
