This does not exist anymore. You can currently:
1. boot -a
2. make a kernel that has root on raidx
1. add the ability to pass the root name through the bootblocks/userconf
2. add a raidctl -A forceroot and obey that.

the real root and then a raid component on wd0e... In that case do we want
to make wd0e the root device because it is on the same drive?

See above... There is a way to disable autoconfiguration, but there is
currently no easy way to get the old behavior? What do you think we should
