I'm setting up multiple systems and ideally I want the same package

there a way to use yum or rpm to configure multiple systems with the
same packages?
What I've done (and I'm on the lookout for a better way) is to right a
script that uses ssh to run yum on each machine.
If there is a way to query yum for the list of installed packages,
that might suffice. Query each computer for the list of installed
packages, get the union of those lists, and install that on each
machine.
Unfortunately, I'm not familiar enough with yum to know if this is
possible.

I guess the best way of doing that is via kickstart
I was thinking about yum... you could do
yum list installed | tail -n +4 | awk '{ print $1 }'
but still there is some work to do.
Maybe "rpm -qa" is a better way to have the list, but still, if you have to
install multiple systems at once, I guess that kickstarting is the best way.
I agree, for install Kickstart is the way to go.
Post-installation, you can use configuration management tools such as puppet
or cfengine to ensure (sets of) packages are installed/not installed as
necessary.

During install kickstart is the way to go. However, after installation
it's the admins personal preference.
I personally just use a series of shell scripts that perform rpm queries
and if statements in an external shell file. If the package is already
installed it skips it, if not it installs it, traps errors on failures,
etc. This has worked quite well for me. This tied together with
ClusterSSH allows me to maintain some 500 workstations quite easily from
the comfort of my Herman Miller Aeron chair.
