I am just trying to move in to the new world of Mark's August snapshot.

The root-path syntax has changed, rather than having a server ip addr 
and the path to mount, it now only includes the pathname and the kernel 
deduces the nfs server by magic.

Before I dive for the source, can anyone explain the magic. And in particular
how I can use an nfs server that is different from the dhcp server?

Thanks
Mark
