| config INIT |
| bool "init" |
| default n |
| select FEATURE_SYSLOG |
| help |
| init is the first program run when the system boots. |
| |
| config DEBUG_INIT |
| bool "debugging aid" |
| default n |
| depends on INIT |
| help |
| Turn this on to disable all the dangerous |
| rebooting stuff when debugging. |
| |
| 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 y |
| depends on FEATURE_USE_INITTAB |
| help |
| When respawn entries are removed from inittab and a SIGHUP is |
| sent to init, this feature will 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 |
| 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 can actually kill |
| wrong process!) |
| |
| config FEATURE_INIT_SCTTY |
| bool "Support running commands with a controlling-tty" |
| default n |
| depends on INIT |
| help |
| If this option is enabled a command starting with hyphen (-) |
| is run in its own session (setsid(2)) and possibly with a |
| controlling tty (TIOCSCTTY). 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 n |
| 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 n |
| 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 |
| help |
| Stop all processes and either halt, reboot, or power off the system. |
| |
| 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 |
