Using Multiple Staging Areas
You can have more than one staging area at a time. Each staging area contains the difference, or delta,
between the Base OS and a patched OS. Staging area stage_1 contains the changes to the Base from
patch_set_1. Staging area stage_2 contains the changes to the Base from only patch_set_2. You can use
the SET command and boot from either staging area stage_1 or stage_2. Refer to Figure G-4 for more
information.
