Having been using this code again myself recently, at the high level,
this is useful.  Having to copy/paste in N UUIDs gets silly.  But I also
wonder..

Is this really an important use case to cover?

The way I see things, would it be possible (and not a pain) to make the
UUID part of the partition string passed to 'gpt write' optional.  If
not passed, generate the UUIDs needed.  What was used would be seen in
'part list' and so forth.
