This > part about the CHOST seems pretty clear to me: > http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=5#doc_chap5_sect2 It is the part where the differences between the stages are described. http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=2#doc_chap2 It is not wrong as it only mentions tweaking initial settings, but I would say that a normal reading is that stage gives you less ability to tweak the *final* system even though this is not stated. allan Stage1 Pros and Cons + Allows you to have total control over the optimization settings and optional build-time functionality that is initially enabled on your system + Suitable for powerusers that know what they are doing + Allows you to learn more about the inner workings of Gentoo - Takes a long time to finish the installation - If you don't intend to tweak the settings, it is a waste of time - Requires a working Internet connection during the installation A Stage2 Approach A stage2 is used for building the entire system from a bootstrapped "semi-compiled" state. Stage2 installs allow you to skip the bootstrap process; doing this is fine if you are happy with the optimization settings that we chose for your particular stage2 tarball. Stage2 Pros and Cons + You don't need to bootstrap + Faster than starting with stage1 + You can still tweak your settings - You cannot tweak as much as with a stage1 - It's still not the fastest way to install Gentoo - You have to accept the optimizations we chose for the bootstrap - Requires a working Internet connection during the installation A Stage3 Approach A stage3 installation contains a basic Gentoo Linux system that has been built for you. You will only need to build a few packages of which we can't decide for you which one to choose. Choosing to go with a stage3 allows for the fastest install of Gentoo Linux, but also means that your base system will have the optimization settings that we chose for you (which to be honest, are good settings and were carefully chosen to enhance performance while maintaining stability). Stage3 is also required if you want to install Gentoo using prebuilt packages or without a network connection. Stage3 Pros and Cons + Fastest way to get a Gentoo base system - You cannot tweak the base system - it's built already -- gentoo-user@gentoo.org mailing list
