Hi Simon,

I didn’t manage yet to get into my profile.
..........................................................
I created a profile with one package "Musescore" in:


home/gfp/Projekte/Musescore

in the directory "Musescore" I have got 2 directories:

"guix-profil" and "guix-profil-1-link"

and

one file:

"guix-profil.lock" (0 Bytes)

..........................................................

I should get into my profile with:

source path/to/some-profile/etc/profile
    …do some stuff…
    exit

Instead, you can run
     guix shell -p path/to/some-profile
     …do some stuff…
     exit
..........................................................

What does it mean in my case?



Kind regards

Gottfried
