 When I use relative paths in my torrc, tor tells me what it will use for
 the PidFile, and then claims it can't find it.
 It also has a similar issue with a relative data directory and
 control_auth_cookie.

 {{{
 Oct 25 11:24:12.784 [warn] Path for PidFile (./data/tor.2/tor.pid) is
 relative and will resolve to
 /home/ubuntu/bwauth/torflow/NetworkScanners/BwAuthority/./data/tor.2/tor.pid.
 Is this what you wanted?
 ...
 Oct 25 11:24:12.000 [warn] Unable to open "./data/tor.2/tor.pid" for
 writing: No such file or directory
 Oct 25 11:24:12.000 [warn] Couldn't open
 "./data/tor.2/control_auth_cookie.tmp" (./data/tor.2/control_auth_cookie)
 for writing: No such file or directory
