This is not the traditional init 38 behavour, but is often what you want in an embedded system where 39 the console is only accessed during development or for maintenance. 40 41config FEATURE_INIT_SYSLOG 42 bool "Enable init to write to syslog" 43 default n 44 depends on INIT 45 46config FEATURE_EXTRA_QUIET 47 bool "Be _extra_ quiet on boot" 48 default y 49 depends on INIT 50 help 51 Prevent init from logging some messages to the console during boot. 52 53config FEATURE_INIT_COREDUMPS 54 bool "Support dumping core for child processes (debugging only)" 55 default n 56 depends on INIT 57 help 58 If this option is enabled and the file /.init_enable_core 59 exists, then init will call setrlimit() to allow unlimited 60 core file sizes.

Allows 71 the name linuxrc to act as init, and it doesn't assume init is PID 1. 72 73 This does not apply to initramfs, which runs /init as PID 1 and 74 requires no special support. 75 76config HALT 77 bool "poweroff, halt, and reboot" 78 default y 79 help 80 Stop all processes and either halt, reboot, or power off the system. 81 82config MESG 83 bool "mesg" 84 default y 85 help 86 Mesg controls access to your terminal by others.
