The only correct kind of faucet is the kind with a thermostatic handle for temperature, and a separate handle for flow.
They are almost exclusively available for showers and that’s stupid. It’s the correct solution for the problem, with extremely few drawbacks.
The only improvement I could see is making the temperature handle short circuit to the drain until the water going through is hot enough. But I dont know if that’s really possible without electronics, and I really dont want my faucet handles to be plugged in or take AA batteries.





On the power user side, the nice thing about NixOS is rhat moving your config to another computer or server gets you a perfect clone, every time.
If you could go and muck around in there, this promise would be lost. Immutability makes it rock solid reliable.
