Devlog 1 - Fixing error checking

In the attempts to expand the services backend and reduce hardcoding, I discovered a slight issue. Error checking was in fact not checking anything. After reading through docs and NixOS source code for the better part of an hour, I missed one line. Alas, enabling error checking also made me discover 10 errors I somehow missed (and which the project worked without fixing? very confusing).
