>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. :-/
