 yum-debug-dump/yum-debug-restore 模块

yum-debug-dump模块是用来导出当前安装的和仓库源里可安装的rpm包信息。dump会输出一个文件在当前目录：yum_debug_dump-<hostname>-<time>.txt.gz。可以用zless命令命令查看

yun-debug-restore导入dump模块输出的txt.gz的包到本地信息库

EXAMPLES        Create a new group metadata file, with a group called yum containing all the packages that start with yum:                yum-groups-manager --name YUM --save groups.xml 'yum*'          After the above command, load the groups.xml data, work with the yum group, make the group not user visible, and remove the yum-skip-broken and yum-priorities packages from it:                yum-groups-manager -n YUM --merge groups.xml --remove yum-skip-broken yum-priorities --not-user-visible          After the above commands, add a description and a translated name to the yum group:                yum-groups-manager -n YUM --merge groups.xml --description 'This is a group with most of the yum packages in it' --translated-name 'en:yum packages'
