Following the commit:

commit b9e5c0a949fa627da55ea53fd71dfa96ad8a2b4b

guix-package: Create ~/.guix-profile when it doesn't exist.

I finally dropped giving the explicit profile parameter to guix-package. This results in the following error when installing a package:

The problem= is that the call to "guix-package --list-available" does not act= ually create anything in the per-user profile directory.

&nb= sp;

After delet= ing $HOME/.guix-profile again and running "guix-package -i hello"= , the per-user profile directory contains a symbolic link guix-profile-1-li= nk to a user environment in the nix store, and a symbolic link guix-profile= to guix-profile-1-link, and $HOME/.guix-profile points to the right thing.= Then "guix-package --list-available" succeeds.

Now I can e= ven remove the hello package, since then the per-user profile directory con= tains a link to the empty user environment in the nix store.

I would sug= gest the following: Before making the $HOME/.guix-profile symlink, check fo= r the guix-profile symlink in the per-user profile directory.
