I can&#x27;t tell if I&#x27;m exposing the wrong port(s) (or rather, PORTing the wrong EXPOSES, please shoot whoever inverted <i>that</i> terminology).  I also can&#x27;t easily tell if I&#x27;m getting relative paths wrong, and I can&#x27;t rapidly iterate on fixing the problem.  That&#x27;s where you really feel the debugging problems.  The drag of day to day troubleshooting of new configuration or tools can still be pretty challenging.<p>Stuff tends to stay working once you get it working though, so that evens up the score a bit, but I&#x27;d really love it if getting there were smoothed out a bit.
