| 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. | |
| 12 | ||
| 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 | |
| 0e4ca02b | 15 | available from: |
