TODO working on changes to this now

First Install on new Machine

NixOS

export HOSTNAME=desired_hostname_for_this_machine (___) export USERNAME=desired_username_for_admin_on_this_machine (josh)

• Follow nixos installation guide: https://nixos.wiki/wiki/NixOS_Installation_Guide

  • Follow until the config is generated

• curl -O https://share.joshuabell.link/nix/onboard.sh && chmod +x onboard.sh && ./onboard.sh

• reboot

• log into USERNAME with password1, use passwd to change the password

• Copy public keys into secrets.nix file

  • cat /etc/ssh/ssh_host_ed25519_key.pub ~/.ssh/id_ed25519.pub

• git clone nixos-config git clone https://github.com/RingOfStorms/dotfiles.git ~/.config/nixos-config

• sudo nixos-rebuild switch --flake ~/.config/nixos-config

• TODO ONBOARD NEW MACHINE CONFIGS, secrets, etc

  • use hostname to make new folders in the repo, copy hardware config, and create config from template. Update flake.nix with top level info needed for this system with ARCH detected.

  • Copy public keys into secrets.nix file

    • cat /etc/ssh/ssh_host_ed25519_key.pub ~/.ssh/id_ed25519.pub

  • git commit -a --author="Bot <bot@joshuabell.dev>" --email="bot@joshuabell.dev" -m "secrets update"

  • rekey system with another onboarded device... (make this offlinable?), push there, pull here

• sudo nixos-rebuild switch --flake ~/.config/nixos-config

• reboot? done

Darwin

• TODO

First Install on new Machine

• First follow nixos installation guide: https://nixos.wiki/wiki/NixOS_Installation_Guide
  • Follow up to generate config command
• in hardware-configuration.nix
  • change to use by-labels made in nixos installation guide (optional but nice for updating device in the future)
• in configuration.nix
  • set networking.hostname to HOSTNAME
  • enable networkmanager
  • uncomment systemPackages and add: git curl
  • add nix.settings.experimental-features = [ "nix-command" "flakes" ];
• Install nixos: cd /mnt sudo nixos-install
• passwd to change root password (if not already prompted to do so)
• reboot

-- TODO come up with a way to pregen keys so onboarding is less stupid with secrets?

• cp -r /etc/nixos ~/nixos_bak Backup configuration

• Checkout this repo into /etc/nixos: rm -rf /etc/nixos git clone https://github.com/ringofstorms/dotfiles /etc/nixos

• Copy the backup into the new /etc/nixos/hosts/HOSTNAME dir mkdir /etc/nixos/hosts/HOSTNAME && cp -r ~/nixos_bak/* /etx/nixos/hosts/HOSTNAME

• copy the existing configuration/other configuration nix of an existing system and edit it to desires state. TODO make this step cleaner/easier...

• switch into flake mode nixos-rebuild switch --flake /etc/nixos[#HOSTNAME] and switch to new system

• Add this host to the top level flake.nix myHosts section

• copy system ssh public key and create a key for user and copy those into the nixos secrets.nix file

  • cat /etc/ssh/ssh_host_ed25519_key.pub
  • cat ~/.ssh/id_ed25519.pub

• Push changes to remote using temp user password

• rekey secrets with any other onboarded system

  • TODO

• copy over this host's ssh public key ( /etc/shh/ed25519 ) into the ./secrets/secrets.nix file - push those up, using another computer re-key all the secrets, push up again

  • pull new secrets down with new added keys and rebuild

• clone neovim setup...

Later updates

• nix flake update /etc/nixos
• nixos-rebuild switch --flake /etc/nixos

Cleanup boot

TODO remove, no longer needed nh handles this

I used the existing windows 100MB boot partition and it fills up constantly. Have to purge old stuff a lot this is how:

• find '/boot/loader/entries' -type f ! -name 'windows.conf' | head -n -4 | xargs -I {} rm {}; nix-collect-garbage -d; nixos-rebuild boot; echo; df

Settings references:

• Flake docs: https://nixos.wiki/wiki/Flakes
• nixos: https://search.nixos.org/options
• home manager: https://nix-community.github.io/home-manager/options.xhtml TODO make an offline version of this, does someone else have this already?

TODO

• Secret management?
  • ssh keys for github/etc
• Use top level split out home manager configurations instead of the one built into the system config...
• Make a flake for neovim and move out some system packages required for that into that flake, re-use for root and user rather than cloning each place?
• EDITOR env var set to neovim
• gif command from video

gif () {
  if [[ -z $1 ]]; then
    echo "No gif specified"
    return 1
  fi
  ffmpeg -i $1 -filter_complex "fps=7,scale=iw:-1:flags=lanczos,split[s0][s1];[s0]palettegen=max_colors=32[p];[s1][p]paletteuse=dither=bayer" $1".gif"
}

• Ensure my neovim undohistory/auto saves don't save .age files as they can be sensitive.
• make sure all my aliases are accounted for, still missing things like rust etc: https://github.com/RingOfStorms/setup
• add in copy paste support with xclip or nix equivalent
