OS X 10.11 El Capitan introduced System Integrity Protection (SIP), which impacts systems management tools in interesting ways. So why am I still talking about createOSXInstallPkg? What about this new startosinstall command? Still more context is needed:
#HOW TO NETBOOT TO EL CAPITAN IMAGE UPGRADE#
createOSXInstallPkg has enabled many interesting OS upgrade scenarios for managed environments, even if machines are initially deployed using traditional imaging methods. Since 2011, Greg Neagle has likely all but stopped building images and over time has convinced many others to as well.

Since these additional packages are installed after the OS is installed, additional bootstrapping can take place when the machine first boots, and provide just enough configuration to have the machine check in to a system for ongoing management.

Without the ability to simply boot the installer from a DVD, this new installer would need some additional tooling to be able to stage its installer setup environment from the currently-running OS, boot into it and complete the installation in an automated fashion.
#HOW TO NETBOOT TO EL CAPITAN IMAGE MAC OS X#
With the release of Mac OS X Lion In 2011, Apple ceased distributing their OS X installers on optical media and switched to the Mac App Store as the primary method of distributing the OS. In environments where Macs are more centrally managed, deploying OS upgrades could be a pain point and involve either a lot of manual work or setting up NetBoot environments that can perform automated OS upgrades. I’ll go into some technical detail about what this tool does and how, but first let’s go back a few years to provide more (and more) context. Since you may be already familiar with the createOSXInstallPkg tool that can also help automate OS X installations, you might be wondering why you should care.

OS X El Capitan’s installer includes a nifty new command-line tool called startosinstall, which can be used to automate installations and upgrades of OS X El Capitan via the command line.
