# Bootchart logger script
# Ziga Mahkovec  
#
# 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
#
# bootchartd will then start itself in background and exec /sbin/init
# (or an alternative init process if specified using bootchart_init=)
#
# To profile a running system, run:
# $ /sbin/bootchartd start; sleep 30; /sbin/bootchartd stop
#
