### BEGIN INIT INFO
# Provides: splashy
# Required-Start: mountkernfs
# Required-Stop: $all
# Default-Start: S
# Default-Stop: 0 6
# Short-Description: A script to calculate the progress percentage for init scripts
# Description: This calculates the progress percentage
# for the scripts in /etc/rcS.d and
# /etc/rc$CURRENT_RUNLEVEL.d.
### END INIT INFO
# Author: Tim Dijkstra <newsuser@famdijkstra.org>,
# Luis Mondesi <lemsx1@gmail.com>
# Luca Capello <luca@pca.it>
#
# If called in the rc[06].d runlevels with the stop target it will start
# splashy in 'shutdown' mode. In the rcS.d runlevel it will try
# to start splashy if it didn't start yet from initramfs.
#
# When it decides to start splashy it will first calculate the
# progress percentage which will be used by the calls to splashy_update
# in the log_end_msg functions.
# This is really simple. We just count them and put them
# in alpha-numeric order. Their percentage is then just
# int( their number on the list * ( 100 / total number on list) )
#
# Of course not all packages use log_end_msg yet, but that
# doesn't matter. The packages that do, will trigger the update
# anyway. This may result in big jumps in the percentage.
# The more scripts start using it, the more granular it will become.
#
#
# This script also needs to detect if Splashy is running and if not
# start it. It's assumed that this will only be run while halt/reboot
# and at RUNLEVEL S.
