Some bits from the 'about' page: 1. The distribution does not provide pre-compiled packages. It only provides package building scripts .... 2. Hadron is fully free. It only contains free(free as in freedom) software. 3. As possible as up-to-date and stable. Reading the first two points together, do I understand correctly that I cannot use the package manager to install proprietary binaries like graphics drivers? Is there room for flexibility akin to Arch's AUR setup for user-management of such packages? What does that third point mean, exactly? Am I dealing with something closer to Debian Stable or a rolling-release system?
