If it's a json file instead of a shell script, I assume you're using a -fb version of targetcli? Then you don't need lio-utils. You can restore the config in /etc/target/saveconfig.json with 'targetcli restoreconfig clear_existing=true', which is what the distro's init scripts should be doing for you, if the service is enabled.
