I am not you, but I need maybe 5min for a config ;) |

and there are more benefits. Smaller binary, more cpu cache free for real data. |

Better performance lies that way. Also, you don't have to wonder about |
| 38 |
processes you did not start. Security is also a point. A smaller codebase in |
| 39 |
use is a saver codebase in use. A lot of bugs only affect kernels with certain |
| 40 |
features turned on - it is very relaxing if you don't have that feature... |
