Hey,

True, that=E2=80=99s super weird!  (Actually I think it=E2=80=99s $HOME, no=
t $USER.)

Currently the =E2=80=98xdg-directory=E2=80=99 procedure (and thus =E2=80=98=
config-directory=E2=80=99,
which by default gives ~/.config/guix) does this:

          (or (getenv variable)
              (and=3D> (or (getenv "HOME")
                         (passwd:dir (getpwuid (getuid))))
                     (cut string-append <> suffix)))

I think giving $HOME higher precedence than /etc/passwd is the =E2=80=9Crig=
ht=E2=80=9D
behavior (the behavior people expect from programs in general), but it=E2=
=80=99s
true that it=E2=80=99s confusing in this case.

Thoughts?

Ludo=E2=80=99.
