I guess it has to do something with the way the root partition is
detected. after the system is installed, mkinitrd has no problem
detecting that the root partition is on a md-device
When running root on an md I only have 2 problems.
I neeed to put in a delay , lets say 2-5 secs, or else one of the
partitions is reported as beeing in use when the raid is set up. The
other problem is that grub is unable to probe, and fails. The
workaround is to not let grub probe, but insted using symlinks. This is
mainly tested on woody, with packages from skolelinux (slightly
modified, grub is 0.93+cvs20030217-0.skolelinux.1, and initrd-tools is
0.1.48.skolelinux.1)

First of all, to test this I would, as others have pointed out, start
with setting up raid manually. If you need help, take a look at a
mini-how that i wrote for skolelinux-servers. It's located at

People who cant set up SWRaid without an automagic installer, should
not run SWRaid. Because they will not add the extra bits that are needed,
like monitoring setup and so one, and therefor SWRaid would only
provide false security.
But yes, it will be nice to have the possibility to set up SWRaid out
of the box.
