How to have a specific node survive when a required node dies from a roslaunch?
Let's say I have nodes A, B, C ... Z. I want for nodes C to Z to die when A dies, but for B to continue executing and ignore that A died. I know I can use the required="true" argument on A in the roslaunch file to kill other nodes when it dies, but is there a way to tell roslaunch to not kill B?
