[求助]误删/var/lib/portage 目录，怎样才能恢复？

figonet

刚刚安装好Gentoo，不小心误删了/var/lib/portage整个目录，怎样才能恢复？

这个目录有什么重要性？revdep-rebuild？

Google了一把，按照regenworld后生成的world才41个程序，而按eix -I --only-names显示的有881个程序，为何差别这么大？我是用funtoo的stage3安装系统，打开原stage3，world只包含git和dhcpd

figonet

regenworld --help
This script regenerates the portage world file by checking the portage
logfile for all actions that you've done in the past. It ignores any
arguments except --help. It is recommended that you make a backup of
your existing world file (/var/lib/portage/world) before using this tool.

world不包含依赖关系

Congratulations!

You deleted the world and the config file.

> pwd
/var/lib/portage
> ls -l
total 44
-rw-r--r-- 1 root portage 40616 2010-01-14 20:52 config
-rw-r--r-- 1 root portage   842 2010-01-25 14:36 world

You can easily restore the world file with your text editor.

But I don't know how to restore the config file.

Maybe emerge -e world can accomplish this if you always run dispath properly after updating your system.

重建 world 文件后，你可以试试看用 emerge --depclean -p 来删不需要的包，里面如果有你想要的，那就手动加入那个文件。
