As long as I've been using gentoo (not long, since 2004) this file has |
| 12 |
always only listed packages you explicitly installed, not any of their |
| 13 |
dependencies. Although, some misguided users accused it on containing all |
| 14 |
their packages. |

*I* still have this file. It did *MOVE* at some point but it current |
| 22 |
incarnation is at /var/lib/portage/world. I've edited the file manually a |
| 23 |
number of times followed by a emerge -A --depclean to clean up my system. |

| 25 |
The file that changed from existing to being auto-calculated was the "edb |
| 26 |
cache" IIRC. From what I understand, these isn't a way to auto-calculate |
| 27 |
world from what's stored in /var/db/pkg and /var/lib/portage (other than |
| 28 |
world and world.backup). |

World isn't auto-generated. |

Edit /var/lib/portage/world. |

Nope, because they weren't listed on the command-line. Just like when you |
| 44 |
emerge kde-meta you only get one package added to world not 300. |

That's one for the portage devs, but I don't /think/ so. |
