Just to be clear, I've never said it was trivial -- but what I have said is that 
it -should- be trivial if people pay attention to this stuff early.

The only thing that has to be done for the split is 'early boot'.  (See my email 
response to Phil..)

As for why, we still have people developing systems with small per-device memory 
that need to do the early boot from a small system, then mount the /usr 
partition from a shared location.  (/usr is often times still mounted RO.. and 
is shared between multiple CPUs within a single device or chasis.)

The usage of this is getting less and less, but we do still get issues from 
customers when things don't work right, so we know people are still doing it.
