Drivers and Secure Boot
RakuOS boots through a locked-down, verifiable chain: Fedora's signed shim and GRUB start the RakuOS kernel, which is signed with the RakuOS key and only loads drivers signed with that key. Drivers aren't built on your PC any more; RakuOS builds and signs them and ships them ready to use.
This is also what Easy Anti-Cheat Linux v2 requires, so RakuOS is ready for it on its side.
