Sounds reasonable.

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.

[1] Though this is of course true of a lot of other things like the
live CD size, logged-in desktop memory usage, etc.
