Just an Idea.
1. Create a /etc/yum directory
2. Create several yum.conf files
Each yum.conf file (YumMain.conf, YumDag.conf, YumWhatever.conf)
will include the repositories that you need AND EXCLUDE ALL OTHER
PACKAGES THAT YOU DO NOT WANT TO TEST IN THAT REPOSITORY
You will have to use a regexp in here
3. Write a script yum_update that will call Yum with each
config file in turn to update the packages.
In theory you can use the parameter exclude inside
each repository, but I believe it will be much too messy,
changing the same Config file all the time.
If you want to automate the process you will have to
create a MetaYum tool
