disklabel fun

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

I have been running a mixture of NetBSD 5, 7 and current i386 DOMUs,
all at different times mounting the same /usr/pkgsrc, which in
reality is raid5e. (So different versions of fsck have had a go after
I panic the DOMU.)

I think I was running NetBSD 5 last yesterday night. Just now I booted
NetBSD-current, and

WARNING: xbd1: total sector size in disklabel (2097152) != the size of xbd1 (104857600)

Where is 2097152 coming from?!
