kern/74352: PXEBoot problems using md as root device

[Erik Norgaard]

I described to problems, they shouldn't be related and I finally 
understood that they are not:

1) NFSCLIENT in the kernel config will override attempts to use a memory 
file as root device

2) Disabling NFSClIENT made the booting interface unavailable after 
mounting the memory disk device

Problem 1 is still there - however 2 was a problem with my memory file 
system. I created a new bare one just capable of running ifconfig and 
both interfaces show up allthough not configured.

Since 2 is not a bug there is a fix to 1, namely disabling NFSCLIENT.
