I don't think it is necessary to port parted. The vendor floppys I have run
into have been
boot floppies running DOS. They could just as well be boot floppies running

For backup purposes it wouldn't be necessary to know the internal format. Most
partitions probably use a standard fs though. (Why reinvent the wheel?)

Both. You would have to add protection to "rm" as well.
The problem I want to solve is the following. In the RedHat/SuSE installers
there is an option
"Use entire drive". At the moment this option wipes any vendor partitions. This
a Bad Thing(TM).
I guess all installer writers could write their own fixes for this (if you
provide a way to
get a partitions partition code... ) or you could pool your efforts and
implement it in parted.
I don't see a really clean way of doing it though :(

Can't you just use cp. Hm... From the manual:
cp [from-device] from-minor to-minor
Can't you copy a partition to a normal file with parted???
parted --script /dev/hda cp 1 /tmp/CompaqDiagnosticPartition
parted --script /dev/hda cp /tmp/CompaqDiagnosticPartition 1
would be really usefull. (It would require that a partition of the correct size
been created. ) I realise you couldn't have files named 1,2 etc. That isn't
much of a
restriction though :)
parted --script /dev/hda create/spawn [minor] /tmp/CompaqDiagnosticPartition
could both create a partition of the correct size and copy
/tmp/CompaqDiagnosticPartition to it

Couldn't you put most stuff in the box by just implementing mkpart for each of
mkpart cdp1 could create a Compaq Diagnostic Partition
mkpartfs cdp1 could do the above and then create the correct fat filesystem.
If Compaq ever puts a diffrent fs on their diagnostic partition just bump the
fstype to cdp2
