- I don't think I'd want to subject my customers to the headache of trying
- to manage patched images. DEC has been moving away from this as fast as
- they can, and for good reason. It's much too easy for a customer to mis-
- type a patch and really screw things up, and if you provide them with a
- file to do it for them, why not provide them with an updated image?

- If you get killed playing the PDP-11 version of Dungeon, it asks you if you
- want to be reincarnated. If you say no, it indignantly protests, "What? Don't
- you trust me? I once patched a running RSX system and it stayed up for 30
- seconds!!"
