Which components are shared between userland and the UEFI environment?

• qqssccfftt 7y ago
  Whatever magic is powering the ability to just run ``systemctl kexec`` and have it automatically reboot into the same kernel you selected at boot without going through UEFI again.

    kexec works fine if you invoke it directly and tell it what kernel+initrd to use, regardless of bootloader; if anything, I'd consider it a failing that systemd can't manage to control a kexec without controlling the bootloader as well

  I don't really understand what you're asking. Edit: Do you mean the component that actually implements the boot loader? I'm not sure if there's any sharing there at this time, it's probably largely as-is from the gummiboot import. This isn't an area I've worked on personally, but you can poke around if you want: https://github.com/systemd/systemd/tree/master/src/boot/efi https://github.com/systemd/systemd/tree/master/src/boot/efi
