- That's correct. If the authorization file disappears then you can go to
- the console and get full access, but you can't login from any other
- terminal. Requiring physical access to the console in this situation is
- not a security hole IMHO, it is similar to bringing the system up in
- single-user mode with Unix, although some Unix systems require a password
- for this. With VMS you can also boot the system with an alternate boot
- file, and then specify the console device as that file, which gives similar
- results to bring up a Unix system in single user mode.
