>Description:
installboot -v /dev/rwd0a /usr/mdec/bootxx_lfsv2 produces a non-booting
system if /dev/rwd0a is in fact a component of an RAIDframe RAID 1 set.

This is because installboot is hard-coded to use ffs_findstage2 for all
partitions of type "RAID", and there is no lfs_findstage2 (how does the
LFS bootblock work at all, even on non-RAID partitions?)

Explicitly using -t raw doesn't seem to work either.  I cannot ascertain
how the stage 2 bootblock is even intended to be found on LFS. :-/
>How-To-Repeat:
See above.
>Fix:

 Hi Thor,

 around the end of September I locally pulled up jdc's changes from June 20
 to the netbsd-3 branch and tested extensively.  I've booted FFSv1, FFSv2
 and LFSv2 root file systems from FS_RAID partitions.

 So, how does that jive with you being unable to boot LFSv2 root with the
 same codebase?

 BTW, I did notice that an FFSv1 boot loader "understands" enough of an LFSv2
 file system to find the second stage, but craps out soon after.
