I'd like to have just one abs location (including all Archlinux
packages, our abslibre and abslibre-mips64el) organized like
ABSROOT/pkgname. We could automatically update from abs in an «arch»
branch and update automatically packages wich need only to add mips64el
(this could be extensible to other arches).

For PKGBUILDS which need more changes it may be good to have a different
file named PKGBUILD.mips64el (or .$arch) and instead of a different repo
for testing a testing folder or a testing-PKGBUILD.

Ideally I think the best thing is to have a git repo per pkgbase and
sync everything with a tool like «git-repo» from google or «gits». That
way we could have contributors to a single packages and they wouldn't
have to download all abs.

Thats for maintaining abs. We could use traditional abs to build using
libretools unchanged.

In most cases this would be an automatic cherry pick and when more
changes are needed it would be a manual process.

I think we shouldn't manage repos as folders, and agree we have no need
to have «multilib» packages if we are maintaining just mips64el. We
could have a script to download packages from selected repos and arches.

I try to use librecommit which makes that, our automatic script could
commit using librecommit too thus making easy this versioning.

This I don't get it

This wouldn't be needed either in the system I propose because mips64el
specific changes would be in a different file.

Again this would be solved.

Agreed, in the meantime of getting this reorganization we shouldn't
merge those repos.
