What I was worried most about was some so-called "helper" app deciding it |
| 34 |
could run grub-mkconfig for me. |
| 35 |
|
| 36 |
Anyway, the functionality isn't going to be used, so best security |
| 37 |
practices say the executable shouldn't even be on the system. |
| 38 |
|
| 39 |
If it's not there, it can't be run, a great solution to both the above. |

Tho the point that it needs a -o parameter to write somewhere is a good |
| 43 |
one as well, certainly ameliorating the problem to some extent. =:^) |
