eWeek has a write up gentoo linux this morning. They say some nice things, but then "hesitate to recommend Gentoo for broad production use" because it "is for the most part a 'from source' distribution" and "the amount of time compilation requires".
They continue testing with WMWare and offer some security update test results. Gentoo didn't fair too badly in those respects. They conclude "it's a distribution that's certainly worth keeping an eye on." It's a nice little read .
