Spacewalk is an Open Source solution for Linux systems management. It’s the community project for Red Hat Network Satellite, since June 2008.
You can do inventory of your systems (hardware and software), install and update software, create custom distribution groups, provide new systems installation with kickstart, manage and deploy configurations, monitor systems, etc.
I’ve not tested it, but after reading its features seems a killer application if you have to manage a vast number of systems and you don’t want to go crazy. I wish I have time to try it.
In case you don’t mind to work with Fedora and/or CentOS. Thanks you Red Hat!
