Resolution

As this is a Linux issue, the best way is to google the error "Executable path is not absolute, ignoring."

I did find quite a lot of hits, notably this one which states that all commands must have an absolute path.

systemd will not accept commands that are not given with absolute path, so to accomplish what you want you need rely on bash

Since this is involving OS and OS customizations, Communities and Google would be the best areas on getting the service to start via boot.  Please keep in mind, you need proper permissions for the service to invoke <EM Home>/bin/EMCtrl.sh.  When attempting to start the EM (or stop) from another path, you need to execute the script using ./ as below

/opt/Introscope/bin/./EMCtrl.sh start

/opt/Introscope/bin/./EMCtrl.sh stop
