A new list has been created: arch-projects.
This list is for development discussion, patches and pull requests for
initscripts, netcfg, dbscripts, devtools (and maybe other projects,
those are the ones I could think of).
Anyone is free to subscribe, but please, no user discussions (keep those
to the forums or arch-general).
Fun fact: There was a mailing list called arch-projects once, and it has
been deleted, but the old archives are still there.
