这是我正在使用的自定义yum.conf：

[main]
cachedir=/var/cache/yum/
debuglevel=2
logfile=/var/log/yum.log
exclude=*-debuginfo
obsoletes=1
gpgcheck=0
reposdir=/dev/null


[base]
name=Fedora 13 - i386
baseurl=file:///media/Fedora\ 13\ i386\ DVD/
enabled=1

[updates]
name=Fedora 13 - i386 - Updates
baseurl=http://mirror.sov.uk.goscomb.net/fedora/linux/updates/13/i386/
enabled=1

当我跑

# yum -c yum.conf --installroot=mnt groupinstall Base

我希望yum能在mnt下安装一切

但它继续说：

[...]
Package irda-utils-0.9.18-10.fc12.i686 already installed and latest version
Package time-1.7-37.fc12.i686 already installed and latest version
Package man-pages-3.23-6.fc13.noarch already installed and latest version
Package talk-0.17-33.2.4.i686 already installed and latest version
Package pam_passwdqc-1.0.5-6.fc13.i686 already installed and latest version
[...]

我试过了

rpm --base=mnt --initdb

然后使用rpm安装fedora-release(在/ mnt下工作并安装了软件包)

但是yum继续说所有软件包都已安装.

有任何想法吗？…
