It actually seems that nothing usefull is written to /var/ by that command and that repeatr might as well NOT be root in that case...

I just realized that the nightly builds at http://repeatr.io/dl/nightly/linux-amd64/repeatr are out of date...

This error message has now been much improved in the "r200" major rewrite.
