+In theory `zmpkg.pl start` should start everything.  In practice, the
+first `zmdc.pl start` invocation does start the daemon but then fails
+to exit, hanging the startup process.  While there is an attempt to
+avoid this in `zmpkg.pl`, it is likely necessary to kill the hanging
+start script, and thus to write a script to do so, to enable reliable
+starting.  This is likely an upstream issue, to be debugged after
+pkgsrc is up to date.
