Building a hyperVConfiguration fails.

[Melody]

When attempting to create a live ISO using a system located in systems/x86_64-install-iso-hyperv/installer the build fails
Error:

Ah, thank you for catching this. I have pushed a fix to the dev branch. Could you try updating the flake input and then building?

[Melody]

Looks like it's building but doesn't seem to boot

Edit: Here is my config for reference - https://gitlab.com/LovingMelody/configsreborn/-/tree/snowfall
ISOs are building without issue in the main branch (pre-snowfall).

@LovingMelody I don't have a hyperv setup to test with so I can't help with debugging the boot issue, but I would imagine at that point it is either down to a configuration of nixos-generators or the system config. I don't see any actual differences in the nixos-generators usage or the nixpkgs input compared to your main branch, so I would imagine there is a difference in the system configuration. I do see that modules/nixos/defaults/default.nix is enabled by default and specifies boot.initrd.systemd.enable. Perhaps a different boot setup is needed for hyperv?

[Melody]

Thanks, for checking, I will look into my configuration further. For future reference, you are able to boot ISO files with following command even the hyperv one qemu-system-x86_64 -boot d -cdrom PATH_TO_ISO
