This will build all my configurations and run `nix flake check`. I'm hoping to eventually move the "build" logic into something in the `checks` flake ouput, which would allow `nix flake check` to handle it for me. #21 tracks that progress at the moment. I had to add a disk-space free action in order to create enough space on the action runner. This could pose a problem for the future..
I'm not currently using Zig nor Rust much, but I am interested in learning both.
I ran `powertop` on my system for about 2-3 hours in order to allow it ample time to determine an accurate measurement of my system's battery usage. It reported 4-6 Whr drain, which honestly seems a little lower than I expected. This battery is also supposedly 51 W..? Either way, I've read online that auto-cpufreq seems to actually perform somewhat better than TLP when it comes to tuning the power drain on a system. From what I can see, even though I may be experiencing placebo, it does seem that my laptop is lasting just a tad longer. Alongside the above changes I scoured the ArchWiki and set some low level things as well. I disabled bluetooth and the HDMI audio transfer, I set the ASPM policy to **powersupersave**, I set the SCSI link policy to **med_power_with_dipm**, and disabled the kernel watchdog. I also switched from using `systemd-timesyncd` to `chrony`, which is generally better for a machine that may not have internet connectivity always, a criteria my laptop perfectly fits.
This software has been abandoned and there are talks on Nixpkgs to remove it. I am also in support of the removal as it's going to slowly become outdated and it's better to pull the plug now than later. We are using `acpilight` now, which contrary to the binary name `xbacklight`, does not _only_ work on X11. This is pretty much a drop-in replacement no special things to worry about here.
The previous nix wrapper wasn't quite "elegantly" crafted. This one attempts to modify arguments in a slightly more durable and extendible manner, and sets `exec` a bit more precisely to ensure proper usage in pretty much all cases. I tried using `nixos-rebuild build --flake .#ref` and it was successful. I also tried `nixos-install --root /random/mount/on/my/live/system --flake .#ref`, and this _also_ worked. These aren't the most durable tests, but it's sufficient for me to know that both are working here, and gives me the confidence to bring it back.
