PureBoot Basic mode provides the full Linux userspace in firmware from Heads without requiring verified boot or a Librem Key. Basic and verified boot can be switched freely without changing firmware, such as if a Librem Key is lost. PureBoot Basic can apply firmware updates from a USB flash drive, and having a complete Linux userspace enables more sophisticated recovery options. Basic mode boots to the first boot option by default, setting a default is not required. This can be configured in the config GUI. Signed-off-by: Jonathon Hall <jonathon.hall@puri.sm>
