grml and bootchart
I just booted grml via a new bootparam called ‘bootchart’ inspired by an article on debian-administration.org.
To generate the picture you will have to save /var/log/bootchart.tgz and copy it to the same location on a system where bootchart-view is available. As you can see in the picture it takes 54 seconds to boot the grml(-large).iso via CD-ROM using default options on my laptop.
