Hi,

thanks very much for your help.

I have got now 3 profiles: EmacsManifest, Musescore, Musik
in:  home/gfp/Projekte/

Now I want them to be activated at login time.

I still am not sure how to do that.

You  wrote:
I should place this code (?) in my /bash profile.

1.
How to do that?
underneath is the profile: EmacsManifest

> GUIX_PROFILE="~/guix-profiles/emacs/emacs"
>> . "$GUIX_PROFILE"/etc/profile
>> export MANPATH="$GUIX_PROFILE/share/man${MANPATH:+:}$MANPATH"
>> export INFOPATH="$GUIX_PROFILE/share/info${INFOPATH:+:}$INFOPATH"
>> ```

>> emacs).

2.
after that, could I uninstall the package emacs in my main profile?
Will my Emacs-manifest profile still be usable/is it independent,
or it will suffer through uninstalling emacs in my main profile?

My aim was to uninstall packages in my main profile and put them in 
separate profiles, so in updating my main profile with less packages
it doesn’t take so much time.

Kind regards

Gottfried
