Aha a perfect canidate use case for GLEP 55[1] that fends off 'why are there multiple versions of the same package' questions and complexities. If you're thinking about having two equal versions with different EAPIs, that's not allowed by GLEP 55: Note that it is still not permitted to have more than one ebuild with equal category, package name, and version. Although it would have the advantage of allowing authors to provide backwards compatible ebuilds, it would introduce problems too. The first is the requirement to have strict EAPI ordering, the second is ensuring that all the ebuilds for a single category/package-version are equivalent, i.e. installing any of them has exactly the same effect on a given system.

Assuming the ebuild changes between foo-1 and foo-2 are mainly due to the change from EAPI=0 to EAPI=2 (which I'd expect to be true in many cases) you could just reuse the foo-1 ebuild for foo-3. If there are major differences between foo-1 and foo-2 not related to the EAPI change then the maintainer probably didn't want foo-2 to become stable anytime soon, so it's at least questionable if foo-3 should go straight to stable in the first place. And adding a new version directly to stable always comes with a risk, you can't eliminate that completely. It's all about risk assessment, and how much work you're willing to do or time you want to spend to minimize the risk. - Backport the security patch to the EAPI=0 ebuild Which sometimes is going to be impossible, require lot of work, and we fall into the risk of bad backported patches when non trivial backport patches are needed (which turns into buggy patches in the stable branch) And sometimes it's a very viable option when patches are provided by upstream. In the end at least one of the above solutions should work in almost every case. It might sometimes cause a bit more work than a bump that doesn't involve any EAPI changes, but that's life. If you have a real case where both suggested solutions aren't realistic I'd like to hear about it, otherwise I think we're wasting time making up solutions for a non-existant problem Marius -- Public Key at http://www.genone.de/info/gpg-key.pub In the beginning, there was nothing.

I couldn't find it documented nor discussed anywhere so I bringing it here. Supposing that anyone can currently add an ebuild using EAPI-2 under the testing branch: what are we going to do if an EAPI-2 ebuild (which are only managed by ~arch package managers) needs to go stable due to some kind of major reason like security? Hypothetical case: foo-1 (eapi-0) marked as stable and foo-2 (eapi-2) with new features marked as testing. A security problem appears affecting both.
