317 | default n | ||
318 | depends on (MSH || LASH || HUSH || ASH) && FEATURE_PREFER_APPLETS | ||
319 | help | ||
320 | This option causes busybox shells to use busybox applets | ||
321 | in preference to executables in the PATH whenever possible. For | ||
322 | example, entering the command 'ifconfig' into the shell would cause | ||
323 | busybox to use the ifconfig busybox applet. Specifying the fully | ||
324 | qualified executable name, such as '/sbin/ifconfig' will still | ||
325 | execute the /sbin/ifconfig executable on the filesystem. This option | ||
326 | is generally used when creating a statically linked version of busybox | ||
327 | for use as a rescue shell, in the event that you screw up your system. | ||
328 | |||
329 | This is implemented by re-execing /proc/self/exe (typically) | ||
330 | with right parameters. Some selected applets ("NOFORK" applets) | ||
331 | can even be executed without creating new process. | ||
332 | Instead, busybox will call <applet>_main() internally. | ||
333 | |||
334 | However, this causes problems in chroot jails without mounted /proc | ||
335 | and with ps/top (command name can be shown as 'exe' for applets | ||
336 | started this way). | ||
337 | # untrue? | ||
338 | # Note that this will *also* cause applets to take precedence | ||
339 | # over shell builtins of the same name. So turning this on will | ||
340 | # eliminate any performance gained by turning on the builtin "echo" | ||
341 | # and "test" commands in ash. | ||
342 | # untrue? | ||
343 | # Note that when using this option, the shell will attempt to directly | ||
344 | # run '/bin/busybox'. If you do not have the busybox binary sitting in | ||
345 | # that exact location with that exact name, this option will not work at | ||
346 | # all. | ||

350 | default n | ||
351 | depends on (MSH || LASH || HUSH || ASH) && FEATURE_PREFER_APPLETS | ||
352 | help | ||
353 | This option causes busybox shells [currently only ash] | ||
354 | to not execute typical fork/exec/wait sequence, but call <applet>_main | ||
355 | directly, if possible. (Sometimes it is not possible: for example, | ||
356 | this is not possible in pipes). | ||
357 | |||
358 | This will be done only for some applets (those which are marked | ||
359 | NOFORK in include/applets.h). | ||
360 | |||
361 | This may significantly speed up some shell scripts. | ||
362 | |||

365 | config CTTYHACK | ||
366 | bool "cttyhack" | ||
367 | default n | ||
368 | help | ||
369 | One common problem reported on the mailing list is "can't access tty; | ||
370 | job control turned off" error message which typically appears when | ||
371 | one tries to use shell with stdin/stdout opened to /dev/console. | ||
372 | This device is special - it cannot be a controlling tty. | ||
373 | |||
374 | Proper solution is to use correct device instead of /dev/console. | ||
375 | |||
376 | cttyhack provides "quick and dirty" solution to this problem. | ||
377 | It analyzes stdin with various ioctls, trying to determine whether | ||
378 | it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line). | ||
379 | If it detects one, it closes stdin/out/err and reopens that device. | ||
380 | Then it executes given program. Opening the device will make | ||
381 | that device a controlling tty. This may require cttyhack | ||
382 | to be a session leader. | ||
383 | |||
384 | Example for /etc/inittab (for busybox init): | ||
385 | |||
386 | ::respawn:/bin/cttyhack /bin/sh | ||
387 | |||
388 | Giving controlling tty to shell running with PID 1: | ||
389 | |||
390 | $ exec cttyhack sh | ||
