is your /var/lib/nfs writable ? do any other rpc services start besides
portmap? It may be a portmapper problem since it's saying it cannot register
the service(which tells me that portmapper is having trouble). I also
see that statd uses /var/lib/nfs(as above).
you may want to look into re-configuring your root filesystems for
read-only-friendly configuration. A while back someone pointed me
to the BBLCD project which creates a bootable linux distro on a CD,
it does a few hacks to the system to redirect files that need to be
written to a ramdisk which is created at startup. It wouldn't be
hard I think to adapt it to network booting. The BBLCD project is
