I wanted to change the port for joystick driver from /dev/input/js0 to /dev/input/js1 using rosparam command.
rosparam set /joy_node/input "/dev/input/js1"
But after reboot, it changed back to js0. Any idea on why rosparam command does not permanently change the port?

First of all, how you're the first value is being set isn't disclosed in your question.
Second of all, according to a question that was answered about 2 hours ago (#q281646) parameters are not stored anywhere. Once rosmaster is shut down all of the parameters are gone. You have to reset the parameters every time you start rosmaster.
