The three laws of users:

1. A user may not injure a sysadmin, or through inaction,
   allow a sysadmin to come to harm.
2. A user must obey the orders given it by sysadmins except
   where such orders would conflict with the First Law.
3. A user must protect its own existence as long as such
   protection does not conflict with the First or Second Law.
