I went to the Gentoo introduction thing at MIT last night. I mostly went because my friend Brian is toying with Gentoo now and I thought it would help him along to get something more than the documentation and it would give me a good idea of how much Gentoo I know. Turns out I know a fair bit. I learned one or two minor things, but generally already knew the material.
One thing of note was that Rajiv said that if you trusted the developers' decisions in regards to building the stage 3 package, you might as well start there and skip the first two stages of installation. I disagree. I don't think most people appreciate the sheer magnitude of effort that has gone into GNU, the Linux kernel, the drivers, Mozilla, Python, X, OpenOffice or other components.
Ooops... Got sidetracked. Anyhow, the introduction was interesting.
