I assume that the NFS-mounted root filesystem is a real distribution.

The simplest way to go is probably to use CentOS or Debian or another ready binary distribution on ARM (or MIPS or PPC or whatever core the embedded system has) possibly on a custom build kernel (if necessary).

Without MMU, it would be truly insane IMHO.
