# Bootchart logger script
#
# Copyright (C) 2009 by Marc Kleine-Budde <mkl@pengutronix.de>
#
# based on: Bootchart logger script from
#
# Ziga Mahkovec <ziga.mahkovec@klika.si>
#
# This script is used for data collection for the bootchart boot
# performance visualization tool (http://www.bootchart.org).
#
# To profile the boot process, bootchartd should be called instead of
# /sbin/init. Modify the kernel command line to include
# init=/sbin/bootchartd or rdinit=/sbin/bootchartd if you use an
# initrd
#
# bootchartd will then start itself in background and exec /sbin/init
# or /init in case of an inird (or an alternative init process if
# specified using bootchart_init=)
