RMC Feature is based on RMC project, systemd-boot, EFI installer to enable a single generic image, built for multiple platforms, automatically applies customization and quirks specific to a type of boards at runtime.
In another word, you will see a single image behaves differently and intelligently according to the type of board it is running on. To Enable this feature: add this line in conf file: EFI_PROVIDER = "rmc-systemd-boot" For a supported board, this feature can : () show and boot with board-specific boot entries in boot menu in live-boot and post-installation. () apply a kernel cmdline fragment to the end of cmdline to boot Linux kernel. This is effective for any boot entry user chooses in boto menu. () create directory and deploy files only for the type of the running board to target's file systems. What left on target after installation is just same as the result from installing a conventional image customized for a single type of hardware. To add support of new boards, a new variable RMC_DISTRO_BOARD_DIRS is the interface to developers. How-to information will be provided with examples in following patches.
