It's significantly uglier and it also skips the helpful headers / sections in the systemd INI files. `[Unit]` and `[Service]` and `[Timer]` represent different layers of execution. Many Nix people got used to the horrible syntax of Nix, I guess? I still find Bitbake significantly more palatable than Nix.
I do appreciate build-time checking but I think this can be solved at systemd side as a separate tool just as effectively.
But my question was around readability: were you able to understand what the snippet I shared is doing?
Re: build-time checks - but systemd hasn’t done it, and I am also unsure where exactly this verification would even take place given systemd’s configuration model. Unless you’re talking about some kind of language server or IDE integration.
Compare it to the alternative of using plain systemd (including command(s) required to enable units).
Also, consider what build-time validation you get prior to starting the unit/timer. Hint: zero.
