Well, there are big differences in how aggressively things are patched. Arch Linux makes a point to strictly minimize patches and avoid them entirely whenever possible. That's a good thing, because otherwise, nonsense like the Xscreensaver situation ensues, where the original developers aggressively reject distro packages for mutilating their work and/or forcing old and buggy versions on unsuspecting users.

Huh? I contribute to Debian; I don't aggressively patch anything. You can too.
