Oh yeah, I was thinking about this yesterday on the way home. I think that the right answer for resizing is "use %pre". Maybe when we come up with a better "language" to describe partitioning, we can integrate resizing. I mean, I guess we could go for part / --size 2500 --resize --onpart sda1 without a clearpart and get to "working". But I don't think it's as clear and I'd rather not muddy those waters > > 3) Only implemented for partitions. Not RAID. Not LVM. I'm not sure > > if we can do RAID. LVM LVs are pretty easy.

So if you're using extents later in the disk, basically, you're screwed right now. Which is kind of sucky. > but we should not even bother with RAID. I don't know that it makes sense either. Realistically, the primary use of this is "I want to install on my box that also has $OTHER_OS". At which point it's not interesting to resize the RAID. > Resizing RAID is sort of an oxymoron anyway. mdadm does actually support it upon looking. It's just a matter of doing mdadm --grow. But yeah, I think punting it for now is all kinds of sane.
