RAID booting

Hi,

I forgot to ask before, but is RAID booting supported on
macppc now? 
The RAID docs say not but only mention NetBSD 2.0 so I
thought things 
might have changed. I want to use a RAID1 or RAID4 scheme,
RAID1 will 
suffice if that's the only option for booting. The system
is already 
booting successfully from the disk I want to use as Disk0 of
the RAID 
set.


Thanks,

Jeff
