There's nothing about NFS that requires that "nobody" be a negative UID;
I suspect future SunOS releases, and the NFS source releases derived
from them, will follow 4.xBSD and S5 and have unsigned UIDs with
"nobody" becoming 65534 or something like that.

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.
