Everest and yoda are on the same subnet. Everest (geo) and yoda (cs) are
NIS masters for different NIS domains and the lab machines are part of the
"cs" NIS domain but it's everest (NIS=geo) that mounts successfully at
boot and yoda (NIS=cs) that doesn't. I'm grasping at straws here including
this additional info.
