How true is this in general? It is usually only a change of the init |
| 8 |
parameter. As far as I heard there is only one exception, /etc/inittab |
| 9 |
being different between just two init systems; if you know more |
| 10 |
exceptions, feel free to list them. So, please prove your statement. |

eselect and wrappers don't operate on themselves, please elaborate. |

Actually no, we're going a step further. The eselect doesn't touch the |
| 21 |
wrapper, but only its config; it's like actually changing brain memory. |

Users can already do this, this isn't a solution. |
| 32 |
|
| 33 |
We want to make this easier towards the user, therefore doing heavy |
| 34 |
discussion to exhaust all the alternatives and maybe someone's |
| 35 |
interested in implementing one of them that appears most feasible. |

I agree, I have mine always available; yet some people are consistent |
| 45 |
in coming up with solutions for when all hell breaks lose. |

Again: Users can already do this, this isn't a solution. See above... |
