There are times when tabs are allowed and times when they are not.
Let's just simply never use tabs for anything. This makes it easy
to find presentations where tabs were accidentally inserted.

The "fancyvrb" package is needed by the minicoredumper presentation. This
is quite a nice package for marking up text. Perhaps other presentations
will start using it also.

The list of companies is a very long and narrow image. It does not
fit well on the slide. I split the image into two columns so that
it is now readable.

For whatever reason, latex did not like this file. It would not
display. I re-exported it in gimp. Now it works.

The only difference between a pres and a print is the config and
tail lines (first and last lines of the .tex). Make this clear
by consolidating all other lines into the main content.

Cleanup build processing:
- support quiet and verbose build output (V=0, 1, or 2)
- cleanup clean targets
- replace for-loops with foreach statements
The build process now supports 3 levels of verbosity. Default (V=0)
provides very little output of the latex tooling, V=1 adds the full
output of the latex tooling and V=2 adds output of the make tooling.

Building latex files may require to re-run the build command more than
once. The make target rules are normally called once.
Make also does not check the dependencies, which are caused by tex
statements (like \input{} or \includegraphics{}).
Both problems are solved by latexmk. This wrapper scans all
dependencies in the .tex file and calls the latex-command until all
depending steps are resolved.
The call of the build-command is forced in make, because the checking,
if a tex-file requires a rebuild is done by latexmk.

Rename the clean target in modules.mk to "clean_texfiles" to avoid

- require gpt images and expect partition layout
and sizes from lx-trainer-vm.xml
- cleanup output
- use dd instead of cat (to allow progress status)
- use parted instead of fdisk (necessary to fix gpt table)
- remove unnecessary partprobe's

These scripts are provided to participants after the training to
allow them to quickly/easily reproduce the many steps of creating
a simple root filesystem from scratch.
These scripts also serve as an excellent reference for trainers
to follow during the live excercises.

In order for the qemu arm vm's to nfs root out-of-the-box, either
the client must specify v3 or the server must restrict itself to
version 2. Rather than expecting special arguments from the client,
force the lx-trainer image to use nfs server version 2.

slides are still available. But they are only available for
