"By uploading content to the Arch User Repository, you irrevocably agree to release it in the public domain, to the extent permitted by law."
GPL would do no harm to Arch either. And pieces of code with less then 10 lines can't have any copyright. The difference in practice is minimal, since it is very unlikely that this piece of code would integrate a non-free software, even including big patches and tricky things.
Since there is little difference, why choose a complicated license such as the GPL over the (much simpler) public domain?
The pratical differente I can see is the need to keep the attribution when it makes sense. If you rewrite everything from scratch, you are the author anyway.
Rewriting from scratch is okay for one PKGBUILD, but I believe we should also allow people to copy the whole database. -- Gaetan
