[ale] Linux Provisioning

[Greg Freemyer]

I have been thinking about how to manage a reasonably large number of
Linux boxes recently. (100+ machines)  All connected via WAN.  

Is the patch and upgrade process I'm most concerned with.

I just saw that redhat has started selling a tool that may work:

http://www.redhat.com/software/rhn/provisioning/

Are there other provisioning tools out there.  Any opensource?
