Enable the login_console_enabled SELinux Boolean

An XCCDF Rule

Description

By default, the SELinux boolean login_console_enabled is enabled. If this setting is disabled, it should be enabled as it allows login from /dev/console to a console session. To enable the login_console_enabled SELinux boolean, run the following command:

$ sudo setsebool -P login_console_enabled on
