Re: [ros-users] remap and machine attributes

Unfortunately the best thing to do is to out-right copy the machine tag.

The alternative moving forward for ROS 1.2+ is to use the <arg> and
$(arg) syntax, which provides actual name reassignment without
duplication of configuration details. That syntax was specifically
introduced (along with if/unless) to provide much more powerful launch
file reuse with respect to multiple machine configurations (including
simulation).
