Add `chown` to Birgittes session

[richelbilderbeek]

Birgitte was in a NAISS meeting, where it was suggested to add chown.

Let's decide on doing so here :-)

[richelbilderbeek]

I would be against adding chown. I will accept Birgitte adding it to her materials.

I feel it does not fit within mine and I although I do see the use and importance of it, I feel the current course content is even more important. But I can be convinced :-)

OK, I will add a brief text about chown to my part of the material

[richelbilderbeek]

Great, then that is decided :-)
