I have the same Nix expression which consistently produces the zerod first-8K binary on my desktop system with bcachefs, while it produces a working binary on my laptop. These machines...

After a lot more differential testing (disabling zstd, zram swap, using different build options, symlinking target dir tmpfs), I suspect this is not related to bcachefs after all, so closing....

Huh. It does indeed look very much like my issue. I've discovered that the zero-header issue disappears if I disable Determinate Nix and switch to vanilla Nix on my system...

Determinate Nix is can be installed on any Linux using [Determinate Nix Installer](https://github.com/DeterminateSystems/nix-installer). It has an option/question which Nix to install, I think. Just to be clear: Determinate Nix _Installer_...
