RE: new to parted

[VomLehn, David]

Hmm. It would be good to know what the partition table mathematics parted uses 
actually are. I'm dealing with a system that creates its own partition table 
(I'm not quite sure how) and parted refuses to deal with them because the 
partitions are not aligned on cylinder boundaries. I see three options:

1. Drop parted and come up with some kludge to wrap around, for example, fdisk.
2. Learn parted partition table mathematics and see if I can get those adopted 
by who writes the software to create partitions
3. Teach parted to handle unaligned partitions.

In general, number 3 would be my perference because it helps out other people 
with my issue, too, but I doubt I have enough time to do that. Number 2 is 
easier but runs into trying to get others to change existing software. Number 1 
is the least desirable and it may not even be possible to do what needs to be 
done this way.

Anyone have any perspective on this? Of course, I'm on a very tight deadline 
and need to decide which way to go almost immediately...
