Of course - and my patch was thought out just to use my changes on SPARC (it 
tests for Sun-disklabels). Still, there are two problems:

- I don't know that much about perl - and thus I have no idea how to tell fdisk 
which partitions to delete, if one changes the disk_config to use fewer 
partitions - currently all partitions listed in the new disk_config, that are 
not preserved, are deleted. - fdisk in debian/testing (and probably unstable 
too) is buggy when using sector-based addressing. Patching it is simple (see 
attached patch for details), but most of you probably don't want that - so I'd 
ask for (perl)-help to use cylinder-based addresses instead of sector-based
