`clan machines build cursa --format sd-card` failed in clan-cli's
post-build secret injection:
Expected directory /nix/store/...-nixos-image-sd-card-...img.zst/sd-card not found in build output
clan-cli assumed $out/<format>/ (only true for iso; sd-card writes
$out/sd-image/) and tried to inject into every format although only iso
has an addFilesScript. Fixed upstream in
patches/upstream-sd-card-secret-injection.patch (pending PR); until it
lands:
- shell.nix: apply patches/clan-cli-image-filepath.patch (the clan-cli
part of the upstream change) to the devshell's clan-cli.
- modules/nixos/sd-card-image.nix: local copy of the upstream
clan.core.image.sd-card.addFilesScript module. Writes the vars tree
directly into the ext4 root partition with debugfs (no boot-time
hook), verifies with cmp + e2fsck. Delete once clan-core ships it.
- cursa imports it and builds its sd-card image without disko.
