that solution has come to mind, and I have seen one case where it was
used (to create, not resize). there's no need even for expect, you can
simply redirect the input because the interaction is well known in
advance, but it's a very ugly solution I hope not to have to implement
for a dozen reasons. At the moment I'm taking all the information I can
with greps and awk, dumping with SFDISK, making the corrections and
loading back. c'est la vie.

Happily, my next task is a bit more interesting. making vmbuilder work
with logical partitions...
