Hmm - this sounds like a good idea ...

On my system /dev/console has r/w access for anyone but this is not
sufficient. I take a look into the kernel sources and there a two ways

- the modified terminal is the controlling terminal for the process or
- the user has the capability to modify terminal settings

What can we do now?
