Is this a good method to start Jboss on Linux with systemd?
I have written a systemd service to start Jboss on Linux and I wonder if there is a more elegant solution. Are there any disadvantages for the method I have chosen? The configuration xml secure_eap_1.xml is a copy of the standalone.xml (or a copy of one of the other templates). Every Jboss AS instance has it own Jboss installation tree in this example.
The systemd unit file: secure_eap_1.service
