I'm not sure why files in DL_DIR would symlink to the local
(pre)mirrors instead of making an independent copy? Mirrors can indeed
move or disappear altogether.
Can you look into where the symlinking happens, and whether that can
be modified or configured differently (maybe also the git history for
that code)?
