Logically, but not technically. |

I like this separation; the package manager takes care of technical |
9 |
requirements, and I get to take care of the logical requirements. |

My point is that when you know that you need ppp (and how could you |
22 |
set USE=ppp otherwise) then it is about equally easy to emerge ppp |
23 |
as it is to set USE=ppp. |

Please read the rest of what I wrote too. :) |

My primary system had 8GB storage until a few years ago when flash |
43 |
prices went down. I was motivated to keep my system clean. If one is |
44 |
space constrained then I think one naturally pays more attention to |
45 |
keeping world small. Disk is still cheap. If it is a problem for me |
46 |
that I have unneeded packages installed, *then* I will start looking |
47 |
at cleaning up. Until then, there's no problem. |

I'm not missing, but I'm saying that it is merely the effect of not |
55 |
managing world very actively. |

|
57 |
I think it's difficult to impossible for a package manager to |
58 |
reliably determine logical requirements from what is a model |
59 |
(USE flags) of technical requirements (link-time dependencies). |
