Does this also fix setting boot.initrd.systemd.enable = true;?
I broke my installation when using it.
My uneducated guess is, that this is the culprit:

Also the readme isn't updated yet with this change.

thanks for the review @MinerSebas!

I'm a bit confused by this pull request.
I can see that we can customize the firmware partition but the root partition as far as I can tell is hardcoded to ext4 or is there a way to override the rootfsImage variable?
And what about the fsType further down?

this change just makes it so you can go through the normal nixos-install flow to setup a pi however you like. For example, I have a pi 5 with a guid partition table and btrfs that I manually partitioned, so I don't import sd-image in that config.

How do you build an image that way?
