    Description

      Some confusing behavior when specifying a configuration file when running on the command line:

      wfong@willcn:~$ ls -la maxscale.cnf 
      -rw-rw-r-- 1 wfong wfong 520 Jul 10 09:50 maxscale.cnf
      wfong@willcn:~$ maxscale -f maxscale.cnf

      wfong@willcn:~$ maxscale -f /home/wfong/maxscale.cnf 
      wfong@willcn:~$ ps aux|grep maxscale
      wfong    30771  2.0  0.6 564864 54656 ?        Ssl  10:32   0:00 maxscale -f /home/wfong/maxscale.cnf

      wfong@willcn:~$ maxscale --version
      MaxScale 1.4.3
      wfong@willcn:~$ 
      

      The documentation and the error message should mention that the complete path must be specified. It would also be good if the error message specified the locations that is has checked (save an admin some time).

      Alternatively, it would be great if a relative position (like just `maxscale -f myfile.cnf`) would be possible as well.

      Thanks!
