I’m trying to use boot.initrd.prepend = [(toString ./acpi_override)] but encounter an error when building initrd itself.
As you can see, this file exists in my flake and option evaluates to a store path:
[azahi@ilmare:~/src/nixfiles]$ file configurations/ilmare/acpi_override
configurations/ilmare/acpi_override: ASCII cpio archive (SVR4 with no CRC)
[azahi@ilmare:~/src/nixfiles]$ nix eval .#nixosConfigurations.ilmare.config.boot.initrd.prepend
[ "/nix/store/rmssa049ivylddy5wbf7hz0rayzxr602-microcode-intel-20240531/intel-ucode.img" "/nix/store/6svpxb9rm61j4jcflm82qwrbgdgvvv7y-source/configurations/ilmare/acpi_override" ]
But that path is inaccessible when building an initrd derivation:
[azahi@ilmare:~/src/nixfiles]$ nix build .#nixosConfigurations.ilmare.config.system.build.initialRamdisk
this derivation will be built:
/nix/store/44macynjnfgvszsisiyx6cqfnh9aam9d-initrd-linux-6.9.6.drv

For full logs, run 'nix log /nix/store/44macynjnfgvszsisiyx6cqfnh9aam9d-initrd-linux-6.9.6.drv'.
The file is git added and is definitely being copied to the store along with the flake source:
[azahi@ilmare:~/src/nixfiles]$ file /nix/store/6svpxb9rm61j4jcflm82qwrbgdgvvv7y-source/configurations/ilmare/acpi_override
/nix/store/6svpxb9rm61j4jcflm82qwrbgdgvvv7y-source/configurations/ilmare/acpi_override: ASCII cpio archive (SVR4 with no CRC)
Why is this happening?
