Lanzaboote / SecureBoot

• Instructions here - Link

1. Create your keys: sbctl create-keys
2. Verify your machine is ready for SecureBoot: sbctl verify - Everything except *-bzImage.efi are signed
3. Enter Secureboot Setup mode in your EFI Settings on the motherboard (F10)
   • Security -> SecureBoot -> Set to Enabled and "Reset to Setup Mode" and exit
4. Enroll the keys: sbctl enroll-keys --microsoft
   • If you wish, you can select --tpm-eventlog, but checksums will change later (ie, at a kernel rebuild)
5. Reboot and verify you are activated: bootctl status

Manual: GPG Keys

1. Import the user private key: gpg --import gpg/users/albert/privkey.asc
2. Mark it as trusted: gpg --edit-key albert@sysctl.io, then type trust, then 5
3. On each new machine, run sudo nix-shell -p ssh-to-pgp --run "ssh-to-pgp -i /etc/ssh/ssh_host_rsa_key -o /etc/nixos/git/keys/hosts/$(hostname).asc"
   • This will output the identifier you add to .sops.yaml
   • Move HOSTNAME.asc to keys/hosts/ and upload to git and rename accordingly.

Secrets

1. Run nix-develop in /etc/nixos/git to import new keys
2. To edit a file: sops secrets/file.yml"
3. When you add a new machine, you must update the secrets files encryption.
   • Run sops updatekeys secrets/file.yaml and commit the change.

Troubleshooting

1. To troubleshoot disko issues, this command can come in handy:

 nix eval .#nixosConfigurations.[CONFIG_NAME].config.disko.devices._config
