So i upgraded to Fedora 15, i must say its going to take a while to get
used it without compiz and general gnome 3 stuff.

First thing i noticed was as its beta there are no official repos.
in the main trunk, you have to use the development ones.

first off move all the files in /etc/yum.repos.d/ *.bak
( we will want to restore these later, when the proper repos come up! )

next

make a new file fedora.repo

Add the following

And work away as normal 🙂
