备份var/cache/pacman/pkg以及pacman。conf的问题？

KenShinXF

问一下
我把/var/cache/pacman/pkg/目录下的所有的pkg文件都备份一下
然后重新安装系统
在把那些备份恢复到var/cache/pacman/pkg文件夹下的话
是不是就是说pacman -S xorg 等等的时候
我就不用从网上在下载那么多文件了，而是直接在我备份的基础上更新或者安装呢

还有就是我的pacman。conf是这样设置repo的

我想问问每个repo下我设置了好几个仓库，是每个都起作用还是，就第一行的起作用，其他的没用？还有就是系统默认有Include = /etc/pacman.d/community
这个文件里面有好多仓库，是不是它在第一行的话其他的就不起作用了，直接是从他的里面更新
还是说先从它下面的第一行更新，要是服务器不通或者网络故障，才会起用Include = /etc/pacman.d/community？

应该按照顺序有个优先级吧，我只在pacman.conf里设了校内的源，速度几个M/S。然后就

2. cd  /etc
3. rm -rf pacman.d

复制代码

没有问题，备份后可以不用再次下载了。
直接修改/etc/pacman.conf
里面[current][extra]等下面的全部注释掉，换成你
像
[current]
#include.......
Server = http://debian.okey.net/archlinux/current/os/i686(这个我用的，你也可以换成你常用的比较快的源)
如果用pacman.d文件里的配置文件的话，默认是从前面的开始，不能连接就自动跳到第二个，依此类推

blance

还有，备份的作用是紧当学要该包才不用下载，如果服务器有更新，而你备份的包比较旧，它还是会默认下载安装新包
再次提醒：要用自己设置的源一定要注释掉include一行，最好不要设置多个仓库，就算要设置也都要一样的顺序，不然有的源更新慢一拍就不好说了：）

我删除后直接用ln -s作了一个/var/cache/pacman/pkg的链接。

用了两年？那那个pkg岂不是超大？

blance

哈哈，看来浏览这个论坛大家都卡嘛

呵呵 ，谢谢大家了

哈哈。。。之前就是由于国外的源一直很慢，搞了几天一个桌面环境都没有pacman下来。这下好设置了。
