If /usr is going to be mounted, we don't have any problem here because 
mountall.sh takes place really early. In this situation, splitting /usr 
is trivial.

What I want to do here is to make system boot up even if /usr is totally 
missing.
Do you think it's suitable for us to support such use case?
