So I was kinda curious what the story was behind the name for FC2 (Tettnang). Honestly, I was a little curious about FC1 (Yarrow), but never looked into it. Historically, Redhat has largely stuck with a naming convention where each release name relates to the immediate predecessor in some way, but not that predecessor’s predecessor (grandparent?). Anyway, this page at the Fedora site seems to cover it to some extent, and here’s a little more discussion on what some of those release names mean (and how they relate) (even more here).
Anyway, check out the Wikipedia’s entry for Tettnang. Guess the Fedora bunch are beer fans.
