connor (he/him)	There was a `--read-only` flag I had forgotten about	03:47:47
connor (he/him)	Okay, it's way faster now and doesn't need a ramdisk. Where as previously it would take about 1m40s on my i9-13900k now it's taking about 20s to do `time nix build -L ".#reports.x86_64-linux.pkgs-cuda-post^*" --builders '' --rebuild`	03:53:40
connor (he/him)	For generating a single report htop shows it was taking about 18% of my RAM (less than 20GB)	03:57:11
connor (he/him)	To clarify, it wasn’t enough to use unsafeDiscardStringContext because the derivation was instantiated as soon as drvPath was evaluated, even before toJSON. Using the read-only argument (which is different than the store URI query parameter of the same name lmao) avoids the instantiating.	06:54:57
