I meant when I am starting Guix, I can choose to use MATE desktop or 
Enlightenment Desktop.
If there is also the option to choose a certain profile, in case I have 
more profils.

When I have choosen MATE desktop,
which profile opens?

I am worried, that, if I create a profile with only one package 
"musescore" in it,
and if that opens, or after creating that profile,
I can't switch to my main profile.

So before creating a profile with only one package musecore in it
I want to be sure how I can switch to that profile and how I can choose 
my other, my main profile.


Kind regards

Gottfried
