The smallnet network loader is meant to be a short term solution for
machines that can't netboot full size kernels until a proper two stage
netboot is available. It isn't the prettiest code around, but it gets
us out of a bind.
To use, "make" in this directory and then in the setnetimage directory:
make KERNEL=/path/to/nfs/install/kernel kernel
and the resultant smallnet.ecoff is suitable for netbooting.
