  12         help
  13           bootchartd is commonly used to profile the boot process
  14           for the purpose of speeding it up. In this case, it is started
  15           by the kernel as the init process. This is configured by adding
  16           the init=/sbin/bootchartd option to the kernel command line.
  17
  18           It can also be used to monitor the resource usage of a specific
  19           application or the running system in general. In this case,
  20           bootchartd is started interactively by running bootchartd start
  21           and stopped using bootchartd stop.

  27         help
  28           Create extended header file compatible with "big" bootchartd.
  29           "Big" bootchartd is a shell script and it dumps some
  30           "convenient" info int the header, such as:
  31             title = Boot chart for `hostname` (`date`)
  32             system.uname = `uname -srvm`
  33             system.release = `cat /etc/DISTRO-release`
  34             system.cpu = `grep '^model name' /proc/cpuinfo | head -1` ($cpucount)
  35             system.kernel.options = `cat /proc/cmdline`
  36           This data is not mandatory for bootchart graph generation,
  37           and is considered bloat. Nevertheless, this option
  38           makes bootchartd applet to dump a subset of it.

  59           a switch to a proper runlevel.

  69           When busybox halt and friends have to call external telinit
  70           to facilitate proper shutdown, this path is to be used when
  71           locating telinit executable.

  91           When respawn entries are removed from inittab and a SIGHUP is

 101           With nonzero setting, init sends TERM, forks, child waits N
 102           seconds, sends KILL and exits. Setting it too high is unwise
 103           (child will hang around for too long and could actually kill
 104           the wrong process!)

 111           If this option is enabled, init will try to give a controlling
 112           tty to any command which has leading hyphen (often it's "-/bin/sh").
 113           More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
 114           If device attached to STDIN_FILENO can be a ctty but is not yet
 115           a ctty for other session, it will become this process' ctty.
 116           This is not the traditional init behavour, but is often what you want
 117           in an embedded system where the console is only accessed during
 118           development or for maintenance.
 119           NB: using cttyhack applet may work better.

 138           If this option is enabled and the file /.init_enable_core
 139           exists, then init will call setrlimit() to allow unlimited
 140           core file sizes. If this option is disabled, processes
 141           will not generate any core files.

 148           Legacy support for running init under the old-style initrd. Allows
 149           the name linuxrc to act as init, and it doesn't assume init is PID 1.
 150
 151           This does not apply to initramfs, which runs /init as PID 1 and
 152           requires no special support.

 159           This is the initial value set by init for the TERM environment
 160           variable. This variable is used by programs which make use of
 161           extended terminal capabilities.
 162
 163           Note that on Linux, init attempts to detect serial terminal and
 164           sets TERM to "vt102" if one is found.

 177           Usually, ttys are owned by group "tty", and "write" tool is
 178           setgid to this group. This way, "mesg y" only needs to enable
 179           "write by owning group" bit in tty mode.
 180
 181           If you set this option to N, "mesg y" will enable writing
 182           by anybody at all. This is not recommended.
