Same as Chromium OS, openFyde adopts the Portage build and packaging system from Gentoo Linux. openFyde uses Portage with certain customisations to support building multiple targets (bootable OS system images) across different hardware architectures from a shared set of sources.
A board defines a target type, it can be either for a family of hardware devices or specifically for one type of device. For example, The board amd64-openfyde is a target type for an openFyde system image that aims to run on most recent PCs with amd64(x86_64) architecture; whilst the rpi5-openfyde board is a target type specifically for the infamous single-board computer Raspberry Pi 5. We usually append -openfyde to the board name in openFyde to differentiate between its siblings for FydeOS.
Each board has a corresponding overlay that defines the configuration for it. This includes details like CPU architecture, kernel configuration, as well as additional packages and USE flags.
This board specifically targets:
rpi5-openfyde is the foundation for FydeOS for You - Raspberry Pi 5 release.
