Yesterday I was thinking of building a Raspberry Pi OS based on Gentoo with all common Gentoo/Linux packages included. Only to find that this is already done! A girl called sakaki (unscary Gentoo girl) is behind genpi64 (gentoo-on-rpi-64bit). It’s a bootable 64-bit Gentoo image for the Raspberry Pi4B, 3B & 3B+, with Linux 4.19, OpenRC, Xfce4, VC4/V3D, camera and h/w codec support, weekly-autobuild binhost.
The system works so good that it’s hard to believe at first. After all Gentoo is a quite complicated Linux system. Some say it’s extremely difficult. If you think so I’m certain you will change your mind when you have tried genpi64! Everything works out of the box. The system also runs very fast if you use a Raspberry Pi 4. Your SD card will be resized automatically after first boot.
Study all included packages in genpi64…
