Hi there,
I love gentoo, but one of its main drawbacks is that you have to wait quite a long time when installing larger packages. Or even the whole system.
There are some ideas around about binary overlays, which could be an option, since there is a binary Firefox, Thunderbird, OOo in the official tree, too. But with binary packages you lose the flexibility of gentoo.
So, why not distribute the emerge process? I used distcc when my laptop was still alive, and it helped pretty much. What if distcc would be configured in a way to work like, say, SETI@home? Do you think that is possible? Of course it has to be run on low priority, but with many participating users I don't think that would be a problem. In combination with ccache, popular packages don't even need to be compiled many times.

What do you think about this idea?

Regards, Christian

derbrain,

This topic comes up fairly regularly. Unless you and your helpers have a lot of internet bandwidth, (100Mbit/sec or more) it won't save any time as you will have to wait for preprocessed files to be set to helpers and again for the results to be downloaded.

ccache helps, as you say but only with second and subsequent builds, when the result you need is already in the cache.
