310 <p>To support alternatives to the official package manager (portage, at the time
311 of this writing), some sane ground rules need to be set. Specifically, no
312 alternative ebuild-based package manager may be added to the tree unless it
313 successfully works with all ebuilds supported by the official package manager.
314 Moreover, no ebuilds may be added to the tree unless they are supported
315 (without change) by the official package manager.</p>
316 </div>
317 <div class="section">
318 <h1><a class="toc-backref" href="#id3" id="specification" name="specification">Specification</a></h1>
319 <ul class="simple">
320 <li>No alternative ebuild-based package manager may be added
321 to the tree unless it successfully works with all ebuilds supported by
322 the official package manager. If an alternative package manager is
323 runtime incompatible with the official package manager, then it
324 must be masked and provide appropriate warnings.</li>
325 <li>No ebuilds may be added to the tree unless they are supported
326 (without change) by the official package manager.</li>
327 </ul>
328 </div>
329 <div class="section">
330 <h1><a class="toc-backref" href="#id4" id="rationale" name="rationale">Rationale</a></h1>
331 <p>The first rule sets a reasonable bar for adding an alternative package
332 manager to the tree. Note that if an ebuild currently in the tree
333 doesn't work with the official package manager, it isn't expected to
334 work with an alternative package manager either. The second rule
335 ensures that an alternative package manager cannot become a de-facto
336 requirement by supporting packages that the official package manager
337 cannot handle.</p>
338 <p>In order to keep this proposal as simple and focused as possible, it has
339 nothing to say about the process by which an alternative package manager
340 might one day become the official package manager. It is assumed that
341 sanity will reign, and no package manager will become official without
342 being able to build installation media, providing a transition path from
343 or to the existing official package manager, etcetera.</p>
344 </div>
345 <div class="section">
346 <h1><a class="toc-backref" href="#id5" id="note" name="note">Note</a></h1>
347 <p>An early criticism of this GLEP was that it fails to address eclasses and
348 profiles. As far as eclasses are concerned, my view is that the above rules
349 suffice, since eclasses only matter in their use in ebuilds. If a package
350 manager can effectively process all ebuilds, then it must be handling the
351 eclasses successfully, too. Profiles, on the other hand, are not addressed
352 here even implicitly.</p>
353 </div>
354 <div class="section">
355 <h1><a class="toc-backref" href="#id6" id="backwards-compatibility" name="backwards-compatibility">Backwards Compatibility</a></h1>
356 <p>Pretty much the whole point, and it's explicit here.</p>
