Re: RAID Controllers and devfs

I hope this E-mail brings attention
to the now _two failing_ RAID controllors.

At the install CD is something what is called devfs.
I don't known enough about devfs to explain what it is.

Things  I know about it are:
 * there is no devfs on the installed computer (as in "it is not used")
 * devfs is about to be removed from the installer
   see http://wiki.debian.org/DebianInstaller/RemoveDevFS for details

That limited knowledge implies that I don't have a clue if
failing RAID controllors and devfs are related.
