yum install packages from ascii list
I have 2 FC 10 systems that need to be kept in exactly the same state. On one system I install what I need / want then do a rpm -qva > list to generate the list of installed packages. Then scp list root@host: to get the list to the remote machine. Then lastly yum install -y $(cat list).
There you go, go make yourself a cuppa and wait!
