This time round I have separate partition for /home as well, but - there is a lot of time and effort spent in downloading software and configuring software. I guess I have my yum logs and I could “replay” all the yum installs into a new distro - but still - a working installation is more than just data in /home and what you get out of the box. Even trivial stuff like fonts to more major stuff like server configs and as I said, installed software. I think best to not go through that every 6 months if not necessary. Also maybe this will allow them to work out the gnome3 issues.
I'll probably stay with F15 until EOL, then go to whatever version is newest at the time.
