config BUSYBOX_CONFIG_CTTYHACK
	bool "cttyhack (2.4 kb)"
	default BUSYBOX_DEFAULT_CTTYHACK
	help
	One common problem reported on the mailing list is the "can't
	access tty; job control turned off" error message, which typically
	appears when one tries to use a shell with stdin/stdout on
	/dev/console.
	This device is special - it cannot be a controlling tty.

	The proper solution is to use the correct device instead of
	/dev/console.

	cttyhack provides a "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).
	On Linux it also checks sysfs for a pointer to the active console.
	If cttyhack is able to find the real console device, it closes
	stdin/out/err and reopens that device.
	Then it executes the 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'

	Starting getty on a controlling tty from a shell script:

	# getty 115200 $(cttyhack)

	help
	This option causes busybox shells to use busybox applets
	in preference to executables in the PATH whenever possible. For
	example, entering the command 'ifconfig' into the shell would cause
	busybox to use the ifconfig busybox applet. Specifying the fully
	qualified executable name, such as '/sbin/ifconfig' will still
	execute the /sbin/ifconfig executable on the filesystem. This option
	is generally used when creating a statically linked version of busybox
	for use as a rescue shell, in the event that you screw up your system.

	This is implemented by re-execing /proc/self/exe (typically)
