The main thing missing -- and I have been working on it, but painfully 
slowly, it seems -- is a kinit which is fully compatible with the 
kernel.  It means replacing *everything* in and beyond 
prepare_namespace() -- all of which should be doable in user space. 
However, there is a ton of legacy crap in there (initrd, ramdisk 
loading, mounting root...) and key to getting it integrated with the 
kernel build is to put the backwards into backwards compatible.

It's not particularly hard work, but it's tedious.
