Special Considerations for Firmware Patches

A firmware patch changes the firmware the next time the patched image is booted. Because the firmware is shared by both the active and inactive system images, there is no ability to have an unchanged copy of the firmware as a fail-safe mechanism. As a result, the benefit of DRD as a Hot Recovery mechanism cannot be provided with firmware patches. Firmware patches set the fileset attribute is_drd_safe to false to supply a checkinstall script that prevents installation in a DRD session.

	IMPORTANT: System administrators need to be aware that any firmware change cannot be reversed by booting a different system image.
