The use case is, given a label, find the UUID and/or the partition number.
I see that 'part' can give me the UUID if I knew the partition number, it
can print the whole table (but I don't think I can use that output
cleanly), and it can list the partition numbers. I don't think I can solve
my problem with 'part' as-is unless I have missed something.

If that's the case would it be alright to add these subcommands to 'part'?
Thank you again,
