That's pretty much what happened in a stage1 or stage2 install. |
| 18 |
Its not cache though as you don't get back the same data as was |
| 19 |
deleted. |

Think 6 month old install. |

Nope. |

If you have just done |
| 35 |
rm -rf /usr/portage ; mkdir /usr/portage ; emerge --sync, |
| 36 |
then emerge -e world gets you the equivelent of emerge --sync && |
| 37 |
emerge world -uDN |
| 38 |
|
| 39 |
Even if you haven't fetched a new tree, you have lost all your old |
| 40 |
binary packages, which you were keeping in case of a broken ~arch |
| 41 |
upgrade that needs to be reverted in a hurry. e.g. one of the nice big |
| 42 |
shiny packages that emerge -e world just updated for you. |
