There was another problem with that “fix”, namely that the daemon ignores normal GC roots pointing to “abnormal” store files like /gnu/store/guix-8uVCz3. This led to the (now abandoned) proposal at <https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00198.html>. I finally came up with a simpler solution in commit 50db7d8: a connection to the daemon is opened for the sake of holding a per-process GC root to that temporary store file. Ludo’.
