As part of some maintenance here, I did a little research as to how to set up NetBoot for various different Macs. For this piece, interchange 'NetBoot' with 'NetInstall' if you're being pedantic - I'm NetBooting the install disc for a particular OS. NetBooting a full install should also be possible using the same techniques.
Mavericks Server (an app free to all developers) has a built-in NetBoot (NetInstall) server GUI, but it only supports a handful of modern versions of OS X. Thankfully, if you follow the instructions in the bootpd manpage you can manually build NetBoot images supporting both PowerPC and Intel Macs going back to OS X v10.2.
Because we can.
