I've been investigating further why my RAID root autoconfiguration
   doesn't work when booting.
   
   I can see in the i386 port that if boot_device is non-null in the
   cpu_rootconf()  (actually findroot() for i386) then it will assume that
   it is already set, which is what RAIDframe does for autoroot.
   
   On sparc64 we don't pay any attention that I can see if this has already
   been set so it looks like the value is set correctly by RAIDframe and
   then overwritten by cpu_rootconf based on what the prom code gave us.
   
   I'm running 1.6.1 but would assume that this is still an issue in current.
   
   Am I completely off base here or did we miss something?


i have this feeling that it's fixed in -current actually... yup:


revision 1.71
date: 2003/01/04 17:00:27;  author: mrg;  state: Exp;  lines: +8 -5
use "booted_device" when calling setroot(), so that raidframe autoconfigured
root works...  now with a "/boot" partition holding /ofwboot & /netbsd i can
have a raidframe root without hard coding root at in my kernel.



try applying this patch to your kernel..
