Several times in my work and freelancing stage organisations I have come across organizations who have deployed rpm based distro for there developers primarily a fedora or a Centos. The only issue was how to update.Cfengine was the preferred choice what I always deployed, Till i discovered Spacewalk. Spacewalk is plain awesome and you can group you machines in categories for specific departments too other than servers, Monitor machines, Audit, Have kicstart deployed, geographically deploy updates or packages. Several Defence related organizations have deployed it where the machine are not connected to external network and updates and packages are taken by the Satelite server (The commercial one by RedHat here). Use it. RedHat is doing a awesome job till date by releasing codes for RedHat satelite server as Spacewalk, Directory server and many more.
