It's more to protect from user envvars leaking into root's |
| 23 |
environment. That's why "service(8)" resets the environment (and then |
| 24 |
sets some, like PATH) on Linux and {Free,Net}BSD. |

I've seen a daemon log in german because a colleague simply used "su" |
| 27 |
to restart it (without using "service"). |

Ubuntu defaults to "sudo" but doesn't force you to use it! If you |
| 35 |
prefer "su", set a root password. |
