Gentoo is fantastic for building a custom rootfs. I much prefer it to Buildroot or Yocto. Google uses the Gentoo package system for ChromeOS. Using the same portage file allows you to trivially pin the exact version of every installed package and if you cache the downloaded source files (/distfiles), you can reproduce the build anytime in the future.

Any suggestions how to get started building a cross rootfs with gentoo? My experience is limited to half a year of gentoo on my laptop in highschool, but I hate yocto with passion and would love to move to gentoo.

Do you have good resource for how to do this?
