<p>The council rejected this GLEP in favor of starting from a package manager |
| 65 |
API and requiring Gentoo package managers in the tree to support that |
| 66 |
API. (That API is still pending, however.)</p> |
| 67 |
</div> |

<div class="section"> |

<h1><a class="toc-backref" href="#id3" id="abstract" name="abstract">Abstract</a></h1> |
| 70 |
<p>To support alternatives to the official package manager (portage, at the time |
| 71 |
of this writing), some sane ground rules need to be set. Specifically, no |
| 72 |
alternative ebuild-based package manager may be added to the tree unless it |
| 73 |
successfully works with all ebuilds supported by the official package manager. |
| 74 |
Moreover, no ebuilds may be added to the tree unless they are supported |
| 75 |
(without change) by the official package manager.</p> |
| 76 |
</div> |
| 77 |
<div class="section"> |
| 78 |
<h1><a class="toc-backref" href="#id4" id="specification" name="specification">Specification</a></h1> |
| 79 |
<ul class="simple"> |
| 80 |
<li>No alternative ebuild-based package manager may be added |
| 81 |
to the tree unless it successfully works with all ebuilds supported by |
| 82 |
the official package manager. If an alternative package manager is |
| 83 |
runtime incompatible with the official package manager, then it |
| 84 |
must be masked and provide appropriate warnings.</li> |
| 85 |
<li>No ebuilds may be added to the tree unless they are supported |
| 86 |
(without change) by the official package manager.</li> |
| 87 |
</ul> |
| 88 |

| 89 |
<div class="section"> |
| 90 |
<h1><a class="toc-backref" href="#id5" id="rationale" name="rationale">Rationale</a></h1> |
| 91 |
<p>The first rule sets a reasonable bar for adding an alternative package |
| 92 |
manager to the tree. Note that if an ebuild currently in the tree |
| 93 |
doesn't work with the official package manager, it isn't expected to |
| 94 |
work with an alternative package manager either. The second rule |
| 95 |
ensures that an alternative package manager cannot become a de-facto |
| 96 |
requirement by supporting packages that the official package manager |
| 97 |
cannot handle.</p> |
| 98 |
<p>In order to keep this proposal as simple and focused as possible, it has |
| 99 |
nothing to say about the process by which an alternative package manager |
| 100 |
might one day become the official package manager. It is assumed that |
| 101 |
sanity will reign, and no package manager will become official without |
| 102 |
being able to build installation media, providing a transition path from |
| 103 |
or to the existing official package manager, etcetera.</p> |

<ul class="simple"> |
| 108 |
<li>An early criticism of this GLEP was that it fails to address eclasses and |
| 109 |
profiles. As far as eclasses are concerned, my view is that the above rules |
| 110 |
suffice, since eclasses only matter in their use in ebuilds. If a package |
| 111 |
manager can effectively process all ebuilds, then it must be handling the |
| 112 |
eclasses successfully, too. Profiles, on the other hand, are not addressed |
| 113 |
here even implicitly.</li> |
| 114 |
<li>Assuming the ebuild specification is successfully finished, then the |
| 115 |
first rule should really replace "all ebuilds supported by the official |
| 116 |
package manager" with "all ebuilds that satisfy the ebuild spec". |
| 117 |
Similarly, in rule two "by the official package manager" should |
| 118 |
read "by the official ebuild spec".</li> |
