That's not /completely/ true:
$ cat /etc/fstab
/dev/md1 / ext3 defaults 1 1
/dev/sdb3 swap swap defaults 0 0
LABEL=SWAP-hda3 swap swap defaults 0 0
/dev/md2 /home ext3 defaults 1 2
/dev/md0 /boot ext2 defaults 1 2
But, the point well taken in the general RAID case...
Also, you clearly don't want *anything* but files that you don't care about
losing on RAID-0. If all of your disks are in a RAID-0, booting is only the
first problem needing a solution.
