I tried with a .config from the live cd, just to see where it gets me. |
| 14 |
Disabled loads of stuff, enabled options I need for my hardware and for |
| 15 |
running KVM here. |

|
| 17 |
This cut my .config from ~76k down to 71k already, and the kernel itself |
| 18 |
got smaller as well: |

nice so far, without much work to do. |

Everything works so far, so ok ... |

I might try the allnoconfig-approach as well, sure! |
