RE: xen with raidframe without grub

[John Hayward <john.hayward%wheaton.edu@localhost>]

Thanks for the help.

Turns out "probable user error".  I had the current file system on raid1a but 
booting was picking up kernel, boot, boot.cfg from raid0a.  Changing boot.cfg 
on raid1a did not change how things were booting.

I guess that boot is smart enough to determine if the partition is raid or not 
and can look for the beginning of the file system offset 64 for raid.

Sorry for the unnecessary interruption.

Yes; I'm running a production system in more or less that way, using 5.0_STABLE 
on amd64.  This is the active boot.cfg line:

menu=Xen (256MB):load /netbsd-DOM0;multiboot /xen.gz dom0_mem=256M console=com1 
com1=9600,8n1

and the relevant sections of what is mounted:

# mount
/dev/raid0a on / type ffs (local)
kernfs on /kern type kernfs (local)
ptyfs on /dev/pts type ptyfs (local)
procfs on /proc type procfs (local)

What do you get if you run 'raidctl -s raid1'?
