Great, the negative IDs were a hassle.

Given a choice between the Yellow Pages and RFS approaches to ID mapping,
I much prefer the RFS style.  Rather than adopt Yellow Pages here when we
first installed NFS, we tossed YP and instead went to a "campus-wide"
global UID scheme.  I'm not recommending that, but it shows what low
regard some sites had for YP.

I don't claim to be an expert, I just watched this stuff happen.
