If by restart from zero mean reinstall then that would be pretty pointless. |

There are easier ways to get to the same result. |

First of all it should be noted that use flags are for optional stuff only. If |
| 16 |
you put -X in your use flags apps that depend on X will still depend on X. |
| 17 |
Only apps that have optional dependency on X will stop depending on X (e.g. |
| 18 |
links). |
| 19 |
|
| 20 |
Further it should be noted that use flags really are your choice. Noone else |
| 21 |
can really you what you need. Still a (few) comments: |

A bit excessive, yes. :) |

You have both alsa and oss in your use flags. OSS is deprecated in favor of |
| 51 |
ALSA and hence if you have alsa enabled in your kernel you really shouldn't |
| 52 |
need optional oss. |
| 53 |
Also you have both arts and esd in your use flags both of which serve the same |
| 54 |
purpose (arts is for kde/esd is for gnome). They are sound daemons that allow |
| 55 |
several apps to use the sound device even if the sound driver allows only one |
| 56 |
app at the same time. Yet modern alsa drivers do allow multiple apps to use |
| 57 |
the sound device at the same time. So IMHO sound daemons are an unnecessary |
| 58 |
overhead. Therefore I would recommend "alsa -arts -esd -oss". |
| 59 |
|
| 60 |
Is there a reason why you have "-nptl" in your use flags?? If not and if you |
| 61 |
do use a 2.6 kernel I recommend you enable it. It is the replacement of |
| 62 |
linuxthreads and it does perform better.. I actually have "nptl nptlonly" in |
| 63 |
mine.. |
| 64 |
|
| 65 |
Other than this I don't intend to comment any further on this. You really are |
| 66 |
the only one who can say what you need. You do have a lot of use flags |
| 67 |
enabled and some would say that it makes your system bloated.. But it really |
| 68 |
is up to you. |

Yes. Run 'emerge --newuse --deep --verbose --pretend' to see what use flags |
| 75 |
changed. It the changed flags with a * and a different color if they changed. |
