You aren't done booting until you complete the init scripts for
runlevel 1.  Having to have an extra copy of the kernel on yet another
device to even get started seems wrong from a minimalist approach, and
the need for sufficient ram for an initrd even more so.  And you
really should be able to mount /usr via nfs while retaining
independent boot/diagnostic capability.
