Display time alongwith the messages in boot.log
 

I would like to check the time it takes for all the services to start by perhaps displaying the giffies. But I am not sure from where the messages are written to boot.log. Are they written individually by each service or by some script?

Maybe this will help http://www.bootchart.org/

Thanks Chris

This is the script you want to look at /etc/rc.d/rc.sysinit (at least on RHEL derivatives)
