Figure G-3. Permanently Applying Patch Changes
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.
