It's one of the earlier Fedora versions--11, 12, or maybe 13.
Despite all the fun had over what the name should be, most people just use F11, F12, and so on.
I think it was Leonidas, Goddard, then Laughlin, for 12, 13, and 14 respectively, but I could be wrong.
To the OP, I've only installed it on CentOS, so can't be of much help there. (And, it was an older version than 6.19).
