[002] Setup
________________________________________________________________________________


--[003] Mounting The efivar Filesystem -----------------------------------------

  To use efibootmgr and other software to manipulate the UEFI boot entries, the
  efivars filesystem must be mounted. This isn't handled automatically by KISS
  due to the security implications in doing so. [1]

  +----------------------------------------------------------------------------+
  |                                                                            |
  |  $ mount -t efivarfs none /sys/firmware/efi/efivars/                       |
  |                                                                            |
  +----------------------------------------------------------------------------+


--[004] Booting The System With An EFISTUB -------------------------------------

  Using an EFISTUB to boot the system removes the need for a bootloader and
  shortens boot times. Ensure that the following options are enabled in your
  kernel: CONFIG_EFI, CONFIG_EFI_STUB

  Run the following command to create a boot entry (replacing example arguments
  with their respective values). X and Y should point to where the ESP is
  located.

  |                                                                            |
  |  $ efibootmgr \                                                            |
  |        --disk /dev/sdX \                                                   |
  |        --part Y \                                                          |
  |        --create \                                                          |
  |        --label "KISS" \                                                    |
  |        --loader /vmlinuz \                                                 |
  |        --unicode 'root=PARTUUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX rw' \ |
  |        --verbose                                                           |
  |                                                                            |
