image-installer-nixos ISO images fail to boot due to missing /dev/root (sysroot-iso.mount fails)

[nvmd]

Cross-posting NixOS/nixpkgs#327187 issue here.

Even though it's an upstream issue, boot.initrd.systemd.enable defaults to false upstream, but here it's unavoidably boot.initrd.systemd.enable = true effectively breaking ISO install images here altogether, therefore I think it makes sense to track this issue here as well.

Tested version: accee00
Both image-installer-nixos-stable and image-installer-nixos-unstable are affected.

Attempting to set boot.initrd.systemd.enable = false; causes the following error on build attempt

Failed assertions:
       - `system.etc.overlay.enable` requires `boot.initrd.systemd.enable`

Dependency on system.etc.overlay.enable seems to be coming from profiles/perlless.nix

Just seeing the issue. I did disable this in our installer: https://github.com/nix-community/nixos-images/pull/257/files and wait for this to be fixed in upstream.

Looks like we are still affected by this somewhat.
