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.

For building, one needs:
- C++20 compiler (e.g., GCC 10.x+, clang 10+)
- CMake 3.19+
- Boost (we're testing with

The build process uses CMake.
A quick-and-dirty build with no fancy options can be as simple as mkdir build && cd build && cmake .. && make && make install.
