-          One common problem reported on the mailing list is "can't access tty;
-          job control turned off" error message which typically appears when
-          one tries to use shell with stdin/stdout opened to /dev/console.
-          This device is special - it cannot be a controlling tty.
-
-          Proper solution is to use correct device instead of /dev/console.
-
-          cttyhack provides "quick and dirty" solution to this problem.
-          It analyzes stdin with various ioctls, trying to determine whether
-          it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
-          If it detects one, it closes stdin/out/err and reopens that device.
-          Then it executes given program. Opening the device will make
-          that device a controlling tty. This may require cttyhack
-          to be a session leader.
-
-          Example for /etc/inittab (for busybox init):
-
-          ::respawn:/bin/cttyhack /bin/sh
-
-          Starting an interactive shell from boot shell script:
-
-          setsid cttyhack sh
-
-          Giving controlling tty to shell running with PID 1:
-
-          # exec cttyhack sh
-
-          Without cttyhack, you need to know exact tty name,
-          and do something like this:
-
-          # exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1'
