We've done this for CentOS5 and  basically created a shell script that
disables yum, sets up smart repositories, get's a list of "base rpms" that
we install and then does a for loop through them. The return code from Smart
on the commandline isn't reliable so you just have to dumbly walk through
and try to install the argument.

Here's the logic - I don't have the source with me right now.

Download yum repo for rpmforge and atrpms
yum update
yum install smart
Download the <base rpms list> from a server (output of rpm -q) we manage
Download the channels list (output from smart channel --show)
Download the mirror list (output from smart mirror --show)
smart channel --add ./<base rpms list>
Add smart mirrors (but I don't remember exactly how)
reload smart cache
smart update
IFS=$'\n'   # in case there are spaces in the name...
for RPM in $(cat <base rpms list>
do
strip the application name out of the rpm file name
smart install application name
done

Some of this is actual BASH code but most is just flow. You'll need to
replace the other stuff with real BASH code. If smart gave reliable rc codes
the script would work better. It just has to brute force it's way through.
