# Bootstrap ISO for NixOS
From this subdirectory directory, run `just iso` to generate the ISO file
## Typical installation flow
1. Flash iso with `sudo dd if=install.iso of=<usb drive> status=progress`
2. Boot image on install host
3. Connect to network via Ethernet or `nmcli`
4. From a donor machine,
`nixos-anywwhere -i <path to install private key> --flake .#<machine> nixos@<ip>`
5. There is a bit of a snag here, but the current protocol is to connect to
ethernet and SSH in using the installer key in order to setup SOPS, this
section will be amended when we figure this out
6. Connect new host to ethernet and SSH in
7. Run `ssh-keyscan <host> | ssh-to-age` to get the age keys for the remote
8. Place the public key into .sops.yaml in the secrets repo at keys.hosts.<host>
9. Run `age-keygen` and place the public key in keys.users.<user>_<host>
10. Create the <host>.yaml file in .sops.yaml and assign *skeleton, the host
key, and the user key
11. Run `just rekey` in the secrets repo and push, then run `just update-secret`
in the primary repo and push.
12. Add new SSH keys to repo
13. Rebuild the system and test for working sops, you can now login locally
