9	  If you say Y here, you are able to get EFI (Extensible Firmware
10	  Interface) variable information via sysfs.  You may read,
11	  write, create, and destroy EFI variables through this interface.

13	  Note that using this driver in concert with efibootmgr requires
14	  at least test release version 0.5.0-test3 or later, which is
15	  available from:
