Great, the negative IDs were a hassle. >Separate issue(s): 1) RFS-style mapping has, I think, been implemented >by Cray, and 2) RFS also has, I think, the same notion of a "nobody" UID. 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.
