+=head2 REMOTE CONTROL RUN COMMAND HANGING
+
+Using the C<run> (or C<launch>) command remotely in a command
+substitution context hangs, ie. don't do (note the backquotes):
+
+ a=`guestfish --remote run`
+
+Since the C<run> command produces no output on stdout, this is not
+useful anyway.  For further information see
