| config INIT |
| bool "init" |
| default y |
| depends on PLATFORM_LINUX |
| select FEATURE_SYSLOG |
| help |
| init is the first program run when the system boots. |
| |
| config FEATURE_USE_INITTAB |
| bool "Support reading an inittab file" |
| default y |
| depends on INIT |
| help |
| Allow init to read an inittab file when the system boot. |
| |
| config FEATURE_KILL_REMOVED |
| bool "Support killing processes that have been removed from inittab" |
| default n |
| depends on FEATURE_USE_INITTAB |
| help |
| When respawn entries are removed from inittab and a SIGHUP is |
| sent to init, this option will make init kill the processes |
| that have been removed. |
| |
| config FEATURE_KILL_DELAY |
| int "How long to wait between TERM and KILL (0 - send TERM only)" if FEATURE_KILL_REMOVED |
| range 0 1024 |
| default 0 |
| depends on FEATURE_KILL_REMOVED |
| help |
| With nonzero setting, init sends TERM, forks, child waits N |
| seconds, sends KILL and exits. Setting it too high is unwise |
| (child will hang around for too long and could actually kill |
| the wrong process!) |
| |
| config FEATURE_INIT_SCTTY |
| bool "Run commands with leading dash with controlling tty" |
| default y |
| depends on INIT |
| help |
| If this option is enabled, init will try to give a controlling |
| tty to any command which has leading hyphen (often it's "-/bin/sh"). |
| More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)". |
| If device attached to STDIN_FILENO can be a ctty but is not yet |
| a ctty for other session, it will become this process' ctty. |
| This is not the traditional init behavour, but is often what you want |
| in an embedded system where the console is only accessed during |
| development or for maintenance. |
| NB: using cttyhack applet may work better. |
| |
| config FEATURE_INIT_SYSLOG |
| bool "Enable init to write to syslog" |
| default y |
| depends on INIT |
| |
| config FEATURE_EXTRA_QUIET |
| bool "Be _extra_ quiet on boot" |
| default y |
| depends on INIT |
| help |
| Prevent init from logging some messages to the console during boot. |
| |
| config FEATURE_INIT_COREDUMPS |
| bool "Support dumping core for child processes (debugging only)" |
| default y |
| depends on INIT |
| help |
| If this option is enabled and the file /.init_enable_core |
| exists, then init will call setrlimit() to allow unlimited |
| core file sizes. If this option is disabled, processes |
| will not generate any core files. |
| |
| config FEATURE_INITRD |
| bool "Support running init from within an initrd (not initramfs)" |
| default y |
| depends on INIT |
| help |
| Legacy support for running init under the old-style initrd. Allows |
| the name linuxrc to act as init, and it doesn't assume init is PID 1. |
| |
| This does not apply to initramfs, which runs /init as PID 1 and |
| requires no special support. |
| |
| config HALT |
| bool "poweroff, halt, and reboot" |
| default y |
| depends on PLATFORM_LINUX |
| help |
| Stop all processes and either halt, reboot, or power off the system. |
| |
| config FEATURE_CALL_TELINIT |
| bool "Call telinit on shutdown and reboot" |
| default y |
| depends on HALT && !INIT |
| help |
| Call an external program (normally telinit) to facilitate |
| a switch to a proper runlevel. |
| |
| This option is only available if you selected halt and friends, |
| but did not select init. |
| |
| config TELINIT_PATH |
| string "Path to telinit executable" |
| default "/sbin/telinit" |
| depends on FEATURE_CALL_TELINIT |
| help |
| When busybox halt and friends have to call external telinit |
| to facilitate proper shutdown, this path is to be used when |
| locating telinit executable. |
| |
| config MESG |
| bool "mesg" |
| default y |
| help |
| Mesg controls access to your terminal by others. It is typically |
| used to allow or disallow other users to write to your terminal |
