Yes, if you have a newer version in a repository and you add that full

But with yum > 2.2.x there is a feature called "includepkgs="

With "includepkgs=" you can make an entry like this in the definition
for the Dag repo:

includepkgs=rsync iptraf

It would then only look at rsync and iptraf from dags repo
