I remember reading in the Release Notes (one of the recent Fred 
releases) something about expanding the lower-numbered UID/GUID 
allocations from a 'pool' of 500 up to 1,000.

Perhaps the above has something to do with it - that and the fact that 
you came the 'upgrade' route (cf a fresh installation). At the same 
time, the guys working on id, authentication, and authorisation may have 
(exclusively) implemented the new regime...

FWIW my clean install's 'first user' does indeed have a UID of 1000.

Apparently there was no concept of 'translating' old id allocs to the 
new scheme. I wonder if there is a post-fact conversion-package?

(haven't looked at migration facilities/concerns - am usually too 
chicken to upgrade between releases, and simply let YUM do its thing or 
(re-)start a new m/c with 'fresh')

I'm a cynic from way-back, so guessed it might be something to do with 
"once was true, no longer is" coupled with a dose of "left hand...right 

A more believable (and factual) explanation is above my pay-grade...
