When installing Ignition as a non-superuser based service you currently need to manually add

[Service]

AmbientCapabilities=CAP_NEY_BIND_SERVICE to the Ignition-Gateway.service file in /etc/systemd/system/

To allow Ignition to run on ports< :1000 (for example we use 443)

When you do an upgrade this does not get preserved, could this be added as a question in the installer after it asks if you want to install the service (with appropriate warnings)?
