Can you clarify what problems you are facing?

I remember one problematic case on foreign distros, that of XDG_DATA_DIRS:

  https://bugs.gnu.org/26202

The environment variable settings that =E2=80=98guix package=E2=80=99 produ=
ces are here
to ensure that software installed with Guix will work as expected.
Ignoring them wholesale (=C3=A0 la Nix) doesn=E2=80=99t sound like a good i=

Thanks,
Ludo=E2=80=99.
