system-config-packages,打算使用光盘作源，不是iso，但是设置出错

Athrun Zala

硬盘没地方了。我需要卸载gcc－4.1
改成gcc-3.4

这里是yum.conf

[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
metadata_expire=1800

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
[local]
baseurl=file:////media/FC_6 i386 DVD
enabled=1


这里是报错

[root@localhost ~]# yum
Loading "installonlyn" plugin
Options Error: Error parsing 'file:////media/FC_6 i386 DVD': URL must be http, ftp, file or https not ""


咋办？
