/dev/hda2 may move if they move the disk.. I think the preferred way (since
it seems fairly hard to 'fix' a disk in the /dev tree under Linux, not so
easy as - say - FreeBSD or NetBSD) is to mount disks from disk labels these
days (ext2 and xfs supports it at least) as then you can move the disk
around. USB, Firewire, external SATA disks will fall under this trap, but
perhaps not internal IDE.. however you can't have both ways :D
