  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.

  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.

  99           This does not apply to initramfs, which runs /init as PID 1 and
 100           requires no special support.

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

 136           More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
 137           If device attached to STDIN_FILENO can be a ctty but is not yet
 138           a ctty for other session, it will become this process' ctty.
 139           This is not the traditional init behavour, but is often what you want
 140           in an embedded system where the console is only accessed during
 141           development or for maintenance.
 142           NB: using cttyhack applet may work better.

 185           When launched as PID 1 and after parsing its arguments, init
 186           wipes all the arguments but argv[0] and rewrites argv[0] to
 187           contain only "init", so that its command line appears solely as
 188           "init" in tools such as ps.
 189           If this option is set to Y, init will keep its original behavior,
 190           otherwise, all the arguments including argv[0] will be preserved,
 191           be they parsed or ignored by init.
 192           The original command-line used to launch init can then be
 193           retrieved in /proc/1/cmdline on Linux, for example.
