Do we have file permission bits for the unauthentificated user? I think
there wouldn't be any security problems if, say, we had files (except
/bin/login) with chmod 6440, 7550, etc. by default. Then an unauthentificated
user is, by default, completely useless and the admin can safely decide
what kind of permissions he/she wants to give out to guests.

such system that spawns rootshell directly is not really a good reference.. :)
