Dear List,

I'm trying to set up a lab with multiple workstations running CentOS  
5. Does anybody knows how to keep the packages in sync among  
workstations? Ideally I want any change made on any machine be able to  
applied to all other machines. Alternatively, to "push" the changes  
(add and/or remove packages) from one central server to all other  
machine is also fine.

P.S.: Sorry for the confusion subject line. I really don't know what's  
the accurate name for the feature I described here.
