I have a script that you can run that rebuilds everything only once and |
| 31 |
it is a complete bottom to top rebuild. No need to do a system then |
| 32 |
world this way. I got it off the forums and I have used it a few times |
| 33 |
and it works very well for me so far. If you want it, I can send it to |
| 34 |
you off list or post it here for everybody that wants to save a copy. I |
| 35 |
have not used it in a while so I'm not sure if portage changes may have |
| 36 |
made it not work anymore. |

Let me know. |
