It would be nice to have the fonts from a Guix package and just add
that to the environment. Where are the fonts from? Do we already have
a Guix package for them or can we pack it?

If there is no Guix-package, I think it is OK to put the font for the
video project just into the repository, at least we know it is a free
font.

I'm still running it with the fonts now, so I can't say it for sure,
but you should try to execute steps 2+3+4 AFTER step 6:

You enter a CONTAINER, and inside the container, only the current
working directory is visible, everything below is just empty. So your
added files and fc-cache changes aren't visible inside the container.

Conversely, everything you mess up inside the container with your
~/.fonts directory should not affect your real users directory (as long
as you don't enter the container from ~ as working directory).

We used VLC to play back the videos. You are right, with totem the
background is green for the slides and light-purple for the CLI
sessions. Maybe there is a problem with the alpha channel?
