I have fedora 10 64-bit installed for some days now.the fcuking thing needs a lot of uninstall and with gnome-package-kit(yumex sucks!) I removed NetworkManager etc(remember Fedora package are case SeNsitive) and bash completion failed to find all packages installed.awright ,figured out with yum.they did a great thing with rpmfusion.
with yum update ,I have to press CTRL+C sometimes with repo(esp india madras IIT Fedora mirror is dead) to continue update.
Overall ,nice package -but Ubuntu ..OK yaar I won't bring Ubuntu/Debian name AGAIN!
