Software License for Icadyptes

Icadyptes will certainly stay open source, but I was hoping for some feedback in regards for what to license the distro as a whole (or parts of it) under. Currently it is on the GPLv3, but I think we may want to put some things into the public domain, such as basic RC scripts.

This isn't totally intuitive, so I will explain how I think distribution licensing works (IANAL). Licensing a distribution applies to the custom portions of the it, such as the init scripts, build scripts, patches, and custom code. Of course the packaged software keeps its own licenses, but we (probably mostly Arch) wrote the PKGBUILDs. At first glance, I think the build scripts are very valuable to someone looking to profit off of a distribution, since there are hundreds of quirks and little things that must be done for the system to work (you can't just ./configure;make;make install to all source tarballs and expect to have a booting system).

I personally like the GPLv3, LGPLv3, and public domain. Some of the Creative Commons licenses look nice, but I haven't researched them too much. Between those three I think we could license the distro into portions. I think stuff like our makepkg hacks should stay under Pacman's GPL, but I'd like most short scripts to be public domain. I don't want to require that people give credit in the source (or binary product) due to some 10 line scripts. On the other hand, I would not like to see the distro as a whole be copied, have a couple tweaks and a name change, and have it closed off and be sold.

Any thoughts or suggestions for this?

Thanks!
