FYI, under the USG UNIX releases (System III, System V, etc.) it's easy to eliminate even the exposure to the OS that logging in gives; you can just tell UNIX to run a program other than the standard "/etc/getty" on some or all terminal ports (in fact, I'm in the middle of writing a screen-oriented "getty/login" at this very minute). (It's possible to do so on other UNIXes, but you either have to tweak "init" to run a different program based on information in the "/etc/ttys" configuration file (the USG releases have already so tweaked "init"), have *every* terminal, including your console DECWriter if that's what you've got, run a replacement "getty", or tweak "getty" to do funny things on selected terminals.) A good reason to wire as little software down in the kernel as you can get away with... Guy Harris {seismo,ihnp4,allegra}!rlgvax!guy
