top -d 0 is also an interesting test for finding bugs.
[jogness] Extended the description of the test.

As discussed with John, this slide set basically only shows the RT tests. So
rename it.
Furthermore, the last two slides are not needed. Especially for scheduling, we
have different slides.

Rather than manually determining and setting the uprobes, use perf
to do it. This allows for the README to become a generic script
that can run out-of-the-box to create the trace.

The daemon slides are sitting in the middle of the scheduling
section. Very odd. Move them to after the Parent/Child slides.
There it makes more sense.

Priority 99 is really reserved for special kernel tasks (such as
migration and watchdog). Mention that it should never be used by
any thing the user does.

In the last 2 trainings I've had participants with batteries going
dead because there was no display for the battery status. The mate
power manager provides this feature. Add it to the image.

Update commands, examples, and output to match rocko.
NOTE: We will checkout a tag instead of a branch!
There are many many slides showing lots (all?) the various
tasks that exist. It is not productive to spend so much time
going through such details. The slides have been completely
commented out. It would probably be good to have a few slides
about this, but that will need to be determined by someone.
The text for many points has been cleaned up (capitalization,
grammar) and in many cases modified to improve clarity. The
general the content of the slides has been preserved.
New slides are added to show function overriding and function
extending.
The kernel/u-boot part of the machine.conf explanation has
been moved to the end of the machine.conf slides.

Capitalization for slides has been cleaned up.
There are many slides about inspection of things like the build
stats. Although interesting, it is not something we should spend
so many slides on. The slides have been commented out.
There are many slides talking about how cleaning can be different
depending on the recipe. We probably don't need slides for this
and can just mention it instead. The slides have been commented
out.

All slide sets show the date on the cover page. We should not
have individual slide sets that do their own thing. If dates are
not wanted, they should be generally removed (or perhaps a
configuration option when building).

The eclipse information is no longer correct for oxygen. It is
almost correct and just needs updating. For that reason it has
been commented out (not deleted).
Capitalization and grammar has been cleaned up on several
places.
The toolchain slides have been moved together and the NFS export
slide moved after.

The various statistic tables were replaced by gnuplot graphs. These
graphs were generated using various scripts. These scripts need to
be added to this repository so that it is easy to update the graphs.
The yocto version table was replaced by a screenshot from

Start the untar processes in parallel. This will take advantage
of file caching and should max out the USB bandwidth.

Tarballs are copied to the USB drives and then unpacked in a
chroot. However, this means the data will travel across the bus
three times! For large layers this is craziness.
Since --numeric-owner is used anyway, just unpack the tarballs
directly.
