 Run tor with a relative path to a config file, e.g.

 {{{
 ./tor -f ../etc/tor/torrc
 }}}

 Issue a SIGHUP to it.  It fails with:

 {{{
 Oct 12 21:37:35.000 [notice] Received reload signal (hup). Reloading
 config and resetting internal state.
 Oct 12 21:37:35.000 [warn] Unable to open configuration file "/[obfuscated
 ]/tor-network/dirauth1/var/lib/tor/../etc/tor/torrc.dirauth".
 Oct 12 21:37:35.000 [err] Reading config failed--see warnings above. For
 usage, try -h.

 }}}
