login is somewhat easier than those alternatives, altho not enough
easier to justify keeping it public.
1. su doesn't change over the whole environment, run .login, etc.
su is reversible by typing ^d. login is and is not, resp.
2. rlogin may be already disabled for various reasonably good
reasons. This leaves only telnet, if anything. telnet doesn't
pass window properties.
