And I submit that my usage is probably pretty common for most desktop |
59 |
Linux users. The only performance issue might be emerge. |

Not going to help me. The backend is on a 32-bit SMP machine. I'm |
66 |
frontend only in my office. |

Yeah, makes sense. |

Yep. I understand the second first hand and probably cannot verify the first. |

As an end-user, non-developer, home-only Gentoo sys admin I don't even |
95 |
know what multilib is although I see it popping up all the time. |
96 |
Please don't feel the need to write up anything major. Point me at |
97 |
some doc that explains why I'd care and I'll read that. Thanks! |
