Is there any guide to netboot NIXOS?

I have a small cluster, and there is one central node serving dhcp, tftp and nfs. I need to netboot all other diskless nodes with it.

The configuration of different diskless nodes are slightly different.

The nixos wiki introduces a script to serve the netbooting, which however does not meet my requirements. It can only serve one configuration.

So I guess I have to fall back to the standard way, i.e., use a dhcp+tftp server.

Is there any guide on this ?

I configured netbooting in BIOS ages with the pxelinux.0, but have little knowledge on netbooting in current efi age.

Thanks.
