What's a 'console user' in the context of unix-like systems?
Whomever logs in locally to X display :0.0, if X is used, or one of the physical ttys if not -- which may include the COM port (if /dev/console is so redirected).
Red Hat assigns permissions to devices based on who logs in. Those are configured in /etc/security/console.perms. Newer udev requires additional considerations.
