Description

https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/fontconfig/default.nix

  fonts = lib.mkForce {
    enableDefaultPackages = false;
    fontconfig.enable = true;
    fontDir.enable = true;
    packages = with pkgs; [
      jetbrains-mono
    ];

but

It would be even better if you could ignore any font at the system level and force custom fonts. Many programs don't even have the option of adjusting fonts. Also for jetmoon there are too many fonts

/nix/store/24k3h17j8pk65ha19bibs9im3328f962-jetbrains-mono-2.304/share/fonts/truetype/JetBrainsMono[wght].ttf: JetBrains Mono:style=Bold
/nix/store/24k3h17j8pk65ha19bibs9im3328f962-jetbrains-mono-2.304/share/fonts/truetype/JetBrainsMono-Italic[wght].ttf: JetBrains Mono:style=Thin Italic

Generally, only these two fonts are needed. Variable fonts contain any font weight.

2. zstd

zstd compression I think it's already been mentioned, but for speed I have two points

Use faster hash algorithms like b3sum Even xxhash https://github.com/Cyan4973/xxHash/wiki/Performance-comparison
For advanced filesystems such as btrfs that support zstd Can duplicate decompression and compression be avoided on updates Compression levels on source servers are usually higher Verify only trusted signatures and checksums
3. O3 pgo lto..

This should be three separate module requests.

The latter two should both have similar ones, but they're not making any progress Mandatory fonts are also difficult. Some software comes with fonts

Yes, but each issue should be tracked individually, so they can be linked to and closed individually. Additionally, the phrasing is not very clear, and multiple issues would help to localize discussion.
