I have an initrd on our firewall/fileserver here at the SOHO since I'm
I'm loading the root fs from a RAID-supported, EVMS drive.  I did this
as a kind of proof of concept to learn how to do it, but at one point a
kernel upgrade forced me to rebuild the initrd manually with a newer
glibc.  It was a strange problem, and a lot of work to fix.  If I could
diagnose and fix _that_ I reckon I can quit whining and fix the
(probably relatively easy) one with my desktop boot.

It's a pity that EVMS is an orphaned project, or was the last time I
checked.  IBM dropped it.  It was and is a pretty slick system.

Ubuntu uses an initrd in all their stuff.  I believe it's involved in
the display of their boot graphic and such.  They've achieved _very_
fast boot times, though, and the loaded system is disk-based.  I know a
lot of Gentoo people look down on Ubuntu, but every distribution I've
ever worked with has its advantages and disadvantages.  Open Source is
about choice :-)

I'm going to nominate Jorge for sainthood!

This is probably close to the point.  Still working on our greenhouse,
but soon I'll get the time to get back on the case with this problem.

Excellent shot, Duncan.  I'll check it.  I won't be using the 2.6.29
kernel again, as per Roman's suggestion, but 2.6.36 instead.
