turtlesim does not clean up its parameters when it terminates

[jihoonl]

I noticed turtlesim_node sets background_r,g,b rosparam when it starts
but it does not deletes it when it dies.

Parameters are conceptionally not being unset when the node which sets them goes away. There is no expectation that parameters are cleaned up by a node either.

turtlesim could set the rgb values to defined values when it starts up. But I would consider that syntactic sugar for this tutorial application. It could actually be considered a good example for the user that the parameters actually stay as they are to demomstrate the persistence of the parameters until the master is restarted.

Therefore I will mark this ticket as "wontfix". Please feel free to comment on the ticket even after it has been closed.

Ok. Thanks for answer.
