I know I'm asking a question that's come up before, but I've not seen a 
   real definitive answer one way or the other (unless I'm looking in the 
   wrong places). Does NetBSD-1.6 or the upcoming 1.6.1 support booting 
   from RAID 1 (using RAIDframe) on sparc? I've seen the suggestion of 
   putting the kernel and bootloader on a small partition with the RAID 
   set to -A root.
   
   Is this still the preferred method, or is there some patch to 
   installboot that'll allow it to install a bootblock on a RAID set 
   without a coredump? I'm fine with either method, but I'd prefer to 
   actually boot from the RAID than do the workaround.


that is the current method for sparc machines.  it's what
i'm successfully using on both sparc & sparc64...
