username is a placeholder!
sudo updateHyperionUser -u root is the best and easiest way to change the user.
Code: updateHyperionUser.sh
"The script updates the user Hyperion is executed by system and service manager (after start-up).
Without arguments it will configure Hyperion being executed under the current user.
The script must be executed as root, i.e. sudo $0
Options:
-u username The user name Hyperion to executed to be with
-h Shows this help message and exits"
A different username can be used instead of root if necessary.
systemctl status hyperion@root would be correct in your case.
