The other thing I will say here is that it's very important for this functionality[1] in particular to ensure we don't regress. It's really easy for almost anything to come along (say, some new ISCSI scanning, or a HAL probe or a font-scanner or...) and hit the boot process and no one notices for quite a while. Here's an example of the "Ts" test that Mozilla has which means "startup performance": http://graphs.mozilla.org/graph.html#tests=[{%22test%22:%2216%22,%22branch%22:%221%22,%22machine%22:%2251%22}] This comes from their "Talos" project: https://wiki.mozilla.org/StandaloneTalos I'm not sure how difficult it is to set up. Now that we have nightly livecd images though (thanks nirik & all), that could be a useful basis for something to feed into a Talos like system if it could be run on infrastructure.
