In reply to @rendakuenthusiast:imperishable.name
once I've transitioned a nixos server onto colmena, what's the correct thing to do with the existing /etc/nixos/configuration.nix file?

It can be something like

(pkgs.writeShellScriptBin "nixos-rebuild" ''
  >&2 echo "This machine is managed by Colmena."
  exit 1
'')

(you may need to tweak its meta.priority otherwise it can conflict with the original one)

rendakuenthusiast: I have the following in a module imported by every host in the hive:

    environment.etc."nixos/configuration.nix".text = ''
      throw '''
        This machine is not managed by nixos-rebuild, but by colmena.
      '''
    '';

Pretty cool:

You can now burn it to a USB with the following command:

Zhaofeng Li: I think there is an opportunity (soonish) to incorporate disko into your install.sh:

https://github.com/divnix/hive/blob/73b486d8d2b5545c6b0bb250324f060afeed6448/comb/lina2358/hardwareProfiles.nix#L4-L6

The parted script can be currently created with:

nix run github:blaggacao/disko/modules --no-write-lock-file -- -f github:divnix/hive?ref=green/lina comb/lina2358/hardwareProfiles/lavinox/disko-config.nix

Just wanted to report on the current status, fysa. Upstream is working on the module branch and things should stabilize soon and look nices 😃
