Archlinux

want some feedback before testing it. How does compare to gentoo or debian for example ?

Ok I installed it, grub has shited in his pants so I re-installed the gentoo's one.
I was disappointed that there's not splitted KDE packages.
Ok, 2 questions :
-gnome-settings-daemon segments fault, I can't launch it.
-Why the fuck Arch put all the gnome/kde stuff in opt ?
