Has anyone had success booting a totally diskless kernel.  That is a kernel
with NFS mounted as root.

I built a kernel with the appropriate options - no file systems except NFS,
NFS_ROOT, NO_SWAP, etc.  build and
configure seem to work find.

The kernel boot seems to run to completion;

trace messages indicated that pagedaemon (pid = 2)  and syncer(pid=3 have
been started.

The sysem panics if I remove init from the /sbin directory in the NFS
server directory.  So it seems that the it is getting invoked.   But a
printf at the beginning doesn't appear on the console.

DDB can be invoked and seems to work - it uses the console.   I don't
really know enough about the kernel to use it though.

On a totally diskless system such as this - who/what created the vnodes in
the /dev directory? could this be 
a problem.

Anyone who want to comment on this is welcome because I'm stuck.
