I see you've been missing this list for a long time. Today it's not |
| 18 |
politically correct to say bluntly "portage" but "package manager" (PM)! |

Um no, we should not stick with packages forever for historical reasons. |

Yes, ebuild author should be careful, OTOH the end users wouldn't have |
| 41 |
to be as much careful as they had to be now when dealing with it themselves. |

Such deps should obviously be transformed to || ( >=coreutils-6.10 |
| 48 |
mktemp) beforehand. |

No, it should probably just state there's a dep conflict (as it does now |
| 54 |
if there are several depends asking for different versions inside one slot). |

Stating dep conflict should be less complexity, and yes it's worth it. |

Sure, legacy and maintainership burden ftw! |

I'm tempted to say "we are not debian" but since I'm not council... :( |
