I did have a look at this a while ago.  FWICT, it would be difficult,
since the XFS implementation depends on kernel stuff.  (The userland
library is basically a wrapper for lots of syscalls/ioctls)

Parted doesn't really work through the kernel (there are cache-coherency
and portability issues).  So, Parted would need architectural changes to
use the xfs library.

I think there are inherrent problems doing resizing like this... I
should finish my little rant about it.  (I've got lots of uni work
ATM :( )

Cheers,
Andrew
