I meant that telling libparted to limit the size of the GPT is specific
to GPT.

I wonder if there is some least common size that we could use then,
which would leave room for all of the various board's boot loaders?
Then again, it might be nice to just be able to specify a size for the
GPT table.  IIRC, there is a way to do that currently using an
environment variable, but that's kind of hacky and was introduced just
for internal testing purposes.
