That is not all. Assuming you get your software RAID set up to your
liking with mdadm on Ubuntu, when you do a dist-upgrade, watch out. I
used mdadm to set up mirrored partitions when I installed Hardy as the
first, fresh install on a new computer with two identical hard disks.
Everything was fine until I eventually did a dist-upgrade to Intrepid.
For some reason that I cannot understand, the dist-upgrade changed the
Grub menu.lst file on only one of the two disks. And I also fail to
grasp why Grub cannot seem to install itself on mda, as it is installed
individually on the two disks. And it always tries to boot from the one
that does not have the updated menu.lst file. I need to go in and
manually copy the /boot folder from the good one to the bad one in
order to get rid of the Grub Error 15 messages. I haven't bothered
because the computer rarely needs to be rebooted - I just select the
previous kernel to boot to.

Ubuntu does need to get its collective head around mdadm. But, having
said that, I found that several other distros do not come with mdadm
either.
