health: read systemd unit state from ListUnits call When we are registering units after listing all units, we did query their state explicitly using another DBus call. This is, however, not required, because ListUnits() method returns both the ActiveState, and the SubState of the unit [1].

Together with sysrepo, this software provides "general system management" of embedded devices. The target platform is anything that runs Linux with systemd. This runs in production on CzechLight SDN DWDM devices.
This component tracks the overal health state of the system, including various sensors, or the state of systemd units. As an operator-friendly LED at the front panel of the appliance shows the aggregated health state.
Firmware can be updated via RAUC, and various aspects of the system's configuration can be adjusted. This includes a firewall, basic network settings, and authentication management.
