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


Comparison

71 seconds - default

grep Required-Start /etc/init.d/*
[..]
/etc/init.d/kerneloops:# Required-Start: $local_fs $remote_fs $named
$network $time $syslog

Why kerneloops needs named?

I added a few dependencies.

why do you hardcode these dependencies? just as a test measurement, what can be achieved?

I'm using something like this:

messagebus depends on rsyslog
haldaemon depends on messagebus
NetworkManager depends on haldaemon

deps for NetworkManager are resolved.

For things with a linear set, yes. But not everything is so fortunate.

Yeah, think what happen if you rsyslog is configured to send logs over
the network ...
