Cobbler is an open source provisioning system that provides a framework for managing your PXE-based installs. It is embedded in the Spacewalk project (and Red Hat Satellite Server 5.x) and can be used standalone if you require a management framework for your PXE boot environment (rather than managing it by hand as we did in Chapter 6, Custom Builds with PXE Booting).
Although the actual use of Cobbler is beyond the scope of this book, it serves as an excellent example for our dynamic inventory section of this book because it is extremely easy to get up and running with.
