Please open up your jaunty and karmic (ureadhead) bootcharts; that goes
for everyone else too ;-)

Now first, please ignore the "time:" bit at the top. That is *NOT* your
boot time, that is simply the number of seconds after boot that
bootchart exited (for whatever reason).

Reading jaunty, scroll down and look at the chart; look at what the last
thing happening before the chart is cut off: It's about 3/4 the way
down:

  [gdm ]
  [Xorg ]
        [sh]
    [xkbcomp]

So this chart is being cut off as soon as the X server is started, and
the other init scripts are finished.

Reading karmic, you'll notice that the chart is much wider and that the
CPU and I/O graphs of the last bit are empty. That's because bootchart
runs longer to capture _more_ of the boot.

Try and find the same gdm/Xorg pattern - it's not at the right hand side
of the graph is it? In fact it's almost exactly in the middle.

jaunty wasn't booting faster - the karmic bootchart just *also* includes
your desktop login as well (since we care about both)
