Hello. I come back regarding my problem of the 'install everything' yum install command to upgrade from a 'server' install to a 'everything' install of CentOS 4, for the follow-up. My DC technician told me to do the following: yum grouplist and then yum groupinstall group_choosen This seems quite a good thing. However, it lacks a 'distro_everything' group that would allow us to instal directly all packages of the distro. We must type each group manually and it's a pain. That would be a must. Maybe it is something to add to the yum functionnality ? Or else to make several top level groups that contain almost everything ? Regards, Daniel
