I had to debug our server death over the phone the other week. I was in
Asia, and it was my mobile phone. (The bill ... hurt).

Fortunately, it wasn't my fault - the motherboard capacitors blew up.

Once we've finished paying the phone bill, we will install a backup...

Root disk moving around during boot is my main problem. But GRUB makes
this easy.

And yes, it does have LVM - but the software RAID array that is LVM'd
seems to need 2 successful boots - one to take on board the re-arranged
disks, and the other to let device-mapper pass this to LVM properly.

2.6 beckons :->

cheers, Rich.
