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. Some selected applets ("NOFORK" applets) - can even be executed without creating new process. - Instead, busybox will call <applet>_main() internally. - - However, this causes problems in chroot jails without mounted /proc - and with ps/top (command name can be shown as 'exe' for applets - started this way). -# untrue? -# Note that this will *also* cause applets to take precedence -# over shell builtins of the same name. So turning this on will -# eliminate any performance gained by turning on the builtin "echo" -# and "test" commands in ash. -# untrue? -# Note that when using this option, the shell will attempt to directly -# run '/bin/busybox'. If you do not have the busybox binary sitting in -# that exact location with that exact name, this option will not work at -# all. - -config BUSYBOX_CONFIG_FEATURE_SH_NOFORK - bool "Run 'nofork' applets directly" - default n - depends on (BUSYBOX_CONFIG_HUSH || BUSYBOX_CONFIG_ASH) && BUSYBOX_CONFIG_FEATURE_PREFER_APPLETS - 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. - -config BUSYBOX_CONFIG_FEATURE_SH_HISTFILESIZE - bool "Use $HISTFILESIZE" - default n - depends on BUSYBOX_CONFIG_HUSH || BUSYBOX_CONFIG_ASH - help - This option makes busybox shells to use $HISTFILESIZE variable - to set shell history size. Note that its max value is capped - by "History size" setting in library tuning section. - - -endmenu |
