parted 'fixlabel' command?

[Matt Domsch]

In dealing with GPT disks, it has been suggested that one drawback is
that you cannot simply 'dd' from a disk of size X onto a disk of size
X+N because the Alternate GPT is stored "at the end of the disk".

This is true, but I think parted can fix this up if you use it to write to the
disk after you dd; set then clear a flag, write a text string label
into it, etc.  The AGPT should get rewritten properly, albeit after
some warnings.

What would you think about a 'fixlabel' or 'growlabel' command,
something like that, which explicitly could handle the fact that the
disk changed, but the partition locations shouldn't?

Thanks,
Matt
