Hi guix, Discovered following behaviour while setting up GNUnet CI:
Given ./gnu/packages/a.scm: ... (source (local-file (dirname (current-filename)))) ... export GUIX_PACKAGE_PATH=$PWD `(current-filename)` returns `#f` when evaluated via `guix environment`, while `guix build` does fine. Is this expected? Am I doing something wrong? The usecase is like https://lists.gnu.org/archive/html/help-guix/2017-04/msg00097.html.
