Does the ordering matter? I have files first then nis. I found this behaviour 
strange as it _is_ the server and the auth files reside there.

Yeah no difference. I'm guessing this probably isn't related.

I blew away the obj dir and recompiled with sources from last night and this 
is now working but ypbind is still hanging.

Is ypbind suppose to hang indefinitely? Does anyone actually have a current 
system running nis?

I was so stoked to see nfs working properly again, figures nis would break on 
me :)
