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 BUSYBOX_CONFIG_FEATURE_BOOTCHARTD_BLOATED_HEADER bool "Compatible, bloated header" default BUSYBOX_DEFAULT_FEATURE_BOOTCHARTD_BLOATED_HEADER depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_BOOTCHARTD_CONFIG_FILE bool "Support bootchartd.conf" default BUSYBOX_DEFAULT_FEATURE_BOOTCHARTD_CONFIG_FILE depends on BUSYBOX_CONFIG_BOOTCHARTD help Enable reading and parsing of $PWD/bootchartd.conf and /etc/bootchartd.conf files. config BUSYBOX_CONFIG_HALT bool "halt (4.3 kb)" default BUSYBOX_DEFAULT_HALT help Stop all processes and halt the system. config BUSYBOX_CONFIG_POWEROFF bool "poweroff (4.3 kb)" default BUSYBOX_DEFAULT_POWEROFF help Stop all processes and power off the system. config BUSYBOX_CONFIG_REBOOT bool "reboot (4.3 kb)" default BUSYBOX_DEFAULT_REBOOT help Stop all processes and reboot the system. config BUSYBOX_CONFIG_FEATURE_WAIT_FOR_INIT bool "Before signaling init, make sure it is ready for it" default BUSYBOX_DEFAULT_FEATURE_WAIT_FOR_INIT depends on BUSYBOX_CONFIG_HALT || BUSYBOX_CONFIG_POWEROFF || BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_CALL_TELINIT bool "Call telinit on shutdown and reboot" default BUSYBOX_DEFAULT_FEATURE_CALL_TELINIT depends on (BUSYBOX_CONFIG_HALT || BUSYBOX_CONFIG_POWEROFF || BUSYBOX_CONFIG_REBOOT) && !BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_TELINIT_PATH string "Path to telinit executable" default BUSYBOX_DEFAULT_TELINIT_PATH depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_INIT bool "init (10 kb)" default BUSYBOX_DEFAULT_INIT select BUSYBOX_CONFIG_FEATURE_SYSLOG help init is the first program run when the system boots. config BUSYBOX_CONFIG_LINUXRC bool "linuxrc: support running init from initrd (not initramfs)" default BUSYBOX_DEFAULT_LINUXRC select BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_USE_INITTAB bool "Support reading an inittab file" default BUSYBOX_DEFAULT_FEATURE_USE_INITTAB depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_LINUXRC help Allow init to read an inittab file when the system boot. config BUSYBOX_CONFIG_FEATURE_KILL_REMOVED bool "Support killing processes that have been removed from inittab" default BUSYBOX_DEFAULT_FEATURE_KILL_REMOVED depends on BUSYBOX_CONFIG_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 BUSYBOX_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 BUSYBOX_DEFAULT_FEATURE_KILL_DELAY depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_INIT_SCTTY bool "Run commands with leading dash with controlling tty" default BUSYBOX_DEFAULT_FEATURE_INIT_SCTTY depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_INIT_SYSLOG bool "Enable init to write to syslog" default BUSYBOX_DEFAULT_FEATURE_INIT_SYSLOG depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_INIT_QUIET bool "Be quiet on boot (no 'init started:' message)" default BUSYBOX_DEFAULT_FEATURE_INIT_QUIET depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_LINUXRC config BUSYBOX_CONFIG_FEATURE_INIT_COREDUMPS bool "Support dumping core for child processes (debugging only)" default BUSYBOX_DEFAULT_FEATURE_INIT_COREDUMPS # not Y because this is a debug option depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_INIT_TERMINAL_TYPE string "Initial terminal type" default BUSYBOX_DEFAULT_INIT_TERMINAL_TYPE depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_INIT_MODIFY_CMDLINE bool "Clear init's command line" default BUSYBOX_DEFAULT_FEATURE_INIT_MODIFY_CMDLINE depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_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
