My understanding was that PKGBUILDs in the Arch distribution would fall under the same licence as Arch, and be part of the larger Arch Linux codebase. With that said, I think that this can be resolved with a statement on the AUR submit page that simply reads: Any package information submitted to the Arch Linux AUR can be included in the main Arch Linux distribution at any time as deemed proper by an Arch Linux Developer or Trusted User. By submitting package information to the Arch Linux AUR you agree to the aforementioned possibility. Or something to that effect, licencing the individual PKGBUILDS will end in tears and legal madness, it will be a long term disaster! We just need the users to understand that if their stuff is awesome, we will most likely use it. And that Arch reserves the right to use it. -Thomas S Hatch
