Between apt-get, up2date, yum or smart and a few more, which one is the best?. Actually I dont have favorite package manager. I just use whatever the server already has on board. If on Ubuntu, apt-get is more than enough. Right now I'm working on Centos 5 that need rrdtool package. By default, the yum repository configuration on Centos 5 does not have rrdtool in it. Thanks to dag wieers for his remarkable effort. Although he had some issue with yum developers previously. Nothing much I can help over there, so back to work.
Well, now create a file called dag.repo in /etc/yum.repos.d/ just like below
[root@yoebuntu yum.repos.d]# cat dag.repo
name=Dag RPM Repository for Red Hat Enterprise Linux
[root@yoebuntu yum.repos.d]# yum install rrdtool
