F9 parallel vs. serial bootscript

[Optimization Kit]

Hi,

I wrote a simple script
http://www.stardust.webpages.pl/files/fedora-upstart/bootscriptconv.py

It creates an upstart wrappers for classic Fedora scripts

Example

start on started rsyslog
start on runlevel 2
start on runlevel 3
start on runlevel 4
start on runlevel 5

stop on runlevel 0
stop on runlevel 1
stop on runlevel 6

console output

script
        /etc/init.d/atd start
end script

pre-stop script
        /etc/init.d/atd stop
end script
