That is certainly useful although I am now using RAID0/1/5 (depending up on partition) along with LVM2 and so they take care of most of this.
The main issue I see is the root= line in grub (or whatever you use) as I am guessing from other posts this doesn't work. I don't think it matters too much for me now as that is a RAID5 partition too. In this age of SATA drives using labels, uuids etc is probably the way to go as my system fell flat on its face when I put a new drive in. Anyone know if the Gentoo kernel can boot using a label? Back to work anyway... Busy, busy, busy...
