Related in upstream (rosdep): https://github.com/ros-infrastructure/rosdep/issues/31 https://github.com/ros-infrastructure/rosdep/pull/312 Apparently its seems far complicated so I won't expect this to be addressed on rosdep side; might as well work it around on my own at least for now.

Experimenting -- on serval, I copied a cron script to /etc/cron.daily instead of symlink. Let's see if the files below get updated tomorrow.
