launchctl config file location?

I'm trying to configure a NetBoot image so that a script will automatically launch on the target machine after it boots from the image I've been using this article as a reference: https://medium.com/@fahimhossain_16989/adding-startup-scripts-to-launch-daemon-on-mac-os-x-sierra-10-12-6-7e0318c74de1 my question is: when the following command is run... # -w flag permanently adds the plist to the Launch Daemon sudo launchctl load -w /Library/LaunchDaemons/com.startup.plist ...where is the resulting permanent configuration entry stored on the hard drive? **To clarify: I'm not asking for the location of the .plist file, I'm asking how/where does the system remember the .plist files that you've configured to run on startup using the 'sudo launchctl load' command?**
