TL;DR:
- Write FromJSON instances to decode rules.json file
- Prefer Text to String and use the OverloadedStrings language extension
- Read /etc/hosts and append the serialized rules.json to the end
Notes:
- I can remove some of the FromJSON instances and use GHC Generics to define
them for me.
TODO:
- Define the systemd timer unit for this to run
- Ensure script can run with root privileges
