of course dual boot is not possible this way. But the idea was to make
sure nothing unplanned happens to the system I currently use everyday.

I can probably live with nullmailer. I'll have a look at it.

I'm not using a predifined layout from /usr/share/X11/xkb/symbols but
some self-defined variant based on us. This means I have to edit a file
under /usr/share but that was the way it was done since I work with X11
(back in the 90s) and so far I haven't found a replacement for it that
allows to fully define own keyboardlayouts.

But in the end the applications depend on configurartion files that need
to be placed somewhere (even if generated or parameterized) by some
scheme code.

I'll have a look at that. Before I encountered these issues I saw it but
didn't understand it's importance.
