CUPS dies after up2date

I decide to run up2date, you know, the "Windows Update"ish thing that appears in the Fedora Core gui. And what happens? CUPS stops printing, that's what. Great. I cannot get CUPS to open up from any othe IP address other than 127.0.0.1

The culprit? Well, it appears that the /etc/cups/cupsd.conf file got overwritten, with a panicky "Block everything!" version. Fortunately, there was a cupsd.conf~ file that appears to be the original one before it got lobotomized. I replaced the busted cupsd.conf with the old one, and everything was back to normal.

"up2date" indeed. And everybody dogs Microsoft! Bah.
