If I remember correctly, I also found UF in 1996.

Amusingly, it was by putting "sunos undocumented features" into, um, I think it was AltaVista that was the state-of-the-art Web search engine at the time? I was trying to sysadmin with almost no training, in way over my head, and hoping the net.gods would bestow me some kind of Clue.

I didn't find what I was looking for, but I got hundreds of hours of entertainment (spread over the time since) instead. :-)
