Goal

Perform the actual nixos-anywhere deployment of lyra once the repo prep and pre-wipe backup are complete.

Acceptance Checklist

  • Stage the pre-generated host key under /tmp/lyra-extra/etc/ssh.
  • Run the nixos-anywhere install against nimmo@192.168.8.146.
  • Allow disko to repartition and install the system.
  • Confirm the machine reboots into NixOS.

Procedure Outline

  1. Build /tmp/lyra-extra with the pre-generated host key pair.
  2. Run:
nix run github:nix-community/nixos-anywhere -- \
  --flake /home/nimmo/nixos-config#lyra \
  --extra-files /tmp/lyra-extra \
  nimmo@192.168.8.146
  1. Wait for the kexec/install/reboot flow to complete.

Notes

This is the destructive cutover step. Do not start it until the backup issue is complete.
