Instead of wasting time configuring and running a location service, I just had a number of slightly different configuration files for redshift (with different manual locations specified) and would just let `.config/redshift.conf` be a symlink to the one corresponding to my current location. (And do some extra work in new locations)
That didn't work with the discussed restriction (but I could easily put all the different configs in `.config/redshift/`.
For now my workaround was simply to replace the symlink with a copy.
