In this case, it is started by the kernel as the init process. This is configured by adding the init=/sbin/bootchartd option to the kernel command line. It can also be used to monitor the resource usage of a specific application or the running system in general. In this case, bootchartd is started interactively by running bootchartd start and stopped using bootchartd stop. config FEATURE_BOOTCHARTD_BLOATED_HEADER bool "Compatible, bloated header" default y depends on BOOTCHARTD help Create extended header file compatible with "big" bootchartd. "Big" bootchartd is a shell script and it dumps some "convenient" info into the header, such as: title = Boot chart for `hostname` (`date`) system.uname = `uname -srvm` system.release = `cat /etc/DISTRO-release` system.cpu = `grep '^model name' /proc/cpuinfo | head -1` ($cpucount) system.kernel.options = `cat /proc/cmdline` This data is not mandatory for bootchart graph generation, and is considered bloat. Nevertheless, this option makes bootchartd applet to dump a subset of it. config FEATURE_BOOTCHARTD_CONFIG_FILE bool "Support bootchartd.conf" default y depends on BOOTCHARTD help Enable reading and parsing of $PWD/bootchartd.conf and /etc/bootchartd.conf files. config HALT bool "halt (4 kb)" default y help Stop all processes and halt the system. config POWEROFF bool "poweroff (4 kb)" default y help Stop all processes and power off the system. config REBOOT bool "reboot (4 kb)" default y help Stop all processes and reboot the system. config FEATURE_WAIT_FOR_INIT bool "Before signaling init, make sure it is ready for it" default y depends on HALT || POWEROFF || REBOOT help In rare cases, poweroff may be commanded by firmware to OS even before init process exists. On Linux, this spawns "/sbin/poweroff" very early. This option adds code which checks that init is ready to receive poweroff commands. Code size increase of ~80 bytes. config FEATURE_CALL_TELINIT bool "Call telinit on shutdown and reboot" default y depends on (HALT || POWEROFF || REBOOT) && !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 INIT bool "init (10 kb)" default y select FEATURE_SYSLOG help init is the first program run when the system boots. config LINUXRC bool "linuxrc: support running init from initrd (not initramfs)" default y select FEATURE_SYSLOG 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 FEATURE_USE_INITTAB bool "Support reading an inittab file" default y depends on INIT || LINUXRC 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 || LINUXRC 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 || LINUXRC help If selected, some init messages are sent to syslog. Otherwise, they are sent to VT #5 if linux virtual tty is detected (if not, no separate logging is done). config FEATURE_INIT_QUIET bool "Be quiet on boot (no 'init started:' message)" default y depends on INIT || LINUXRC config FEATURE_INIT_COREDUMPS bool "Support dumping core for child processes (debugging only)" default n # not Y because this is a debug option depends on INIT || LINUXRC 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 INIT_TERMINAL_TYPE string "Initial terminal type" default "linux" depends on INIT || LINUXRC help This is the initial value set by init for the TERM environment variable. This variable is used by programs which make use of extended terminal capabilities. Note that on Linux, init attempts to detect serial terminal and sets TERM to "vt102" if one is found. config FEATURE_INIT_MODIFY_CMDLINE bool "Clear init's command line" default y depends on INIT || LINUXRC help When launched as PID 1 and after parsing its arguments, init wipes all the arguments but argv[0] and rewrites argv[0] to contain only "init", so that its command line appears solely as "init" in tools such as ps. If this option is set to Y, init will keep its original behavior, otherwise, all the arguments including argv[0] will be preserved, be they parsed or ignored by init. The original command-line used to launch init can then be retrieved in /proc/1/cmdline on Linux, for example. endmenu
