I have no clue on the current state. I have had this setup for a while
now...

Filesystem Type Size Used Avail Use% Mounted on
/dev/sdb1 ext4 579M 125M 413M 24% /bootalt
/dev/sda1 ext4 579M 125M 413M 24% /boot
Everything else is on various raid1 partitions. The above is kept
identical via a nightly rsync. The boot block stuff is installed on
both sda & sdb. And yup, would have to swap positions if sda fails.
Oh, don't forget to raid the swap partition also; you want *everything*
to be able to continue after a drive failure.
