	The ash shell is the most bash compatible and full featured one,

	Note that selecting this option does not switch on any bash

	/bin/bash (sym)link and run scripts which start with
	#!/bin/bash line.

	Many systems use it in scripts which use bash-specific features,
	even simple ones like $RANDOM. Without this option, busybox
	can't be used for running them because it won't recongnize
	"bash" as a supported applet name.

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)
config BUSYBOX_CONFIG_HUSH
	bool "hush (68 kb)"
	default BUSYBOX_DEFAULT_HUSH
	help
	hush is a small shell. It handles the normal flow control
	constructs such as if/then/elif/else/fi, for/in/do/done, while loops,
	case/esac. Redirections, here documents, $((arithmetic))
	and functions are supported.

	It will compile and work on no-mmu systems.

	It does not handle select, aliases, tilde expansion,
	&>file and >&file redirection of stdout+stderr.

	command (not entire shell), fg/bg builtins work. Without this option,
	"cmd &" still works by simply spawning a process and immediately
	prompting for next command (or executing next command in a script),

	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)
	with right parameters.

	However, there are drawbacks: it is problematic in chroot jails
	without mounted /proc, and ps/top may show command name as 'exe'
	for applets started this way.

	help
	This option causes busybox shells to not execute typical
	fork/exec/wait sequence, but call <applet>_main directly,
	if possible. (Sometimes it is not possible: for example,
	this is not possible in pipes).

	This will be done only for some applets (those which are marked
	NOFORK in include/applets.h).

	This may significantly speed up some shell scripts.

	This feature is relatively new. Use with care. Report bugs
	to project mailing list.

	help
	Allow scripts to be compressed and embedded in the busybox
	binary. The scripts should be placed in the 'embed' directory
	at build time. Like applets, scripts can be run as
	'busybox SCRIPT ...' or by linking their name to the binary.

	This also allows applets to be implemented as scripts: place
	the script in 'applets_sh' and a stub C file containing
	configuration in the appropriate subsystem directory.
