230 appears when one tries to use a shell with stdin/stdout on
232 This device is special - it cannot be a controlling tty.
234 The proper solution is to use the correct device instead of
237 cttyhack provides a "quick and dirty" solution to this problem.
238 It analyzes stdin with various ioctls, trying to determine whether
239 it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
240 On Linux it also checks sysfs for a pointer to the active console.
241 If cttyhack is able to find the real console device, it closes
242 stdin/out/err and reopens that device.
243 Then it executes the given program. Opening the device will make
244 that device a controlling tty. This may require cttyhack
245 to be a session leader.

249 ::respawn:/bin/cttyhack /bin/sh

255 Giving controlling tty to shell running with PID 1:

537 This option causes busybox shells to use busybox applets
538 in preference to executables in the PATH whenever possible. For
539 example, entering the command 'ifconfig' into the shell would cause
540 busybox to use the ifconfig busybox applet. Specifying the fully
541 qualified executable name, such as '/sbin/ifconfig' will still
542 execute the /sbin/ifconfig executable on the filesystem. This option
543 is generally used when creating a statically linked version of busybox
544 for use as a rescue shell, in the event that you screw up your system.
546 This is implemented by re-execing /proc/self/exe (typically)
547 with right parameters.
549 However, there are drawbacks: it is problematic in chroot jails
550 without mounted /proc, and ps/top may show command name as 'exe'

561 this is not possible in pipes).
563 This will be done only for some applets (those which are marked
