I write permanent 4-letter names on my disks with a marker
pen. Computers too. The partitions are just 2-digit suffixes.
Names makes it easier to remember that PC wasp contains
disks faye and chad, for example.

Thanks for the example. It's long been a disappointment that
there's no GRUB_DISABLE_LINUX_LABEL=true parameter in
/etc/default/grub. For years I've post-processed grub.cfg
with a shell script to replace the UUIDs with LABELs by
using data from /run/udev/data/b* (and making a few other
tweaks). But I can see I ought to be doing more pruning.
Cheers,
David.
