+ bool "bootchartd"
+ default n
+ help
+ bootchartd is commonly used to profile the boot process
+ for the purpose of speeding it up. 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.

+ system.cpu = `grep '^model name' /proc/cpuinfo | head -1` ($cpucount)

+ 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.
