# Theming
* To change system-wide themes, you need to change the following:
### gnome
  1.  `desktops/gnome.nix` - Change the imports at the bottom.
  2.  `users/albert/gnome-conf.nix` - Change the variables at the top.
### neovim
  1.  `home-manager/neovim.nix` - Change the following:
      * `plugins = with pkgs.vimPlugins` - Add your theme under "Themes"
      * `extraConfig` - Change the `colorscheme` and `AirlineTheme` sections
### hyprland
  1.  `hosts/$HOSTNAME/home-manager/hyprland/hyprland-conf.nix` - Change the `WALLPAPER_DIR` variable in `".config/hypr/start.sh".text`
  2.  `hosts/$HOSTNAME/home-manager/hyprland/hyprland-conf.nix` - Change `col.active_border` and `col.inactive_border` in the `general` section.
  3.  `home-manager/bash.nix` - Update the `sessionVariable` variable `GTK_THEME`
### waybar
  1.  `hosts/$HOSTNAME/home-manager/hyprland/waybar-conf.nix` - Update all relevant colors.  Possibly make configs for colorschemes and import them.
### swaylock
  1.  `hosts/$HOSTNAME/home-manager/hyprland/swaylock-conf.nix` - Update all relevant colors.  Possibly make configs for colorschemes and import them.
### kitty
  1.  `home-manager/kitty.nix` - Update the content of `home.file.".config/kitty/theme.conf".text`
### Firefox
  1.  `home-manager/firefox.nix` - Change the entry under "# Theming"
### btop
  1.  `home-manager/btop.nix` - Set `color_theme`
### bash / powerline
  1.  `home-manager/bash.nix` - Set `theme` in `programs.powerline-go.settings`
### neofetch
  1.  `home-manager/neofetch.nix` - Update the contents of `home.file.".config/neofetch/config.conf".text`

# 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 `nix-shell -p ssh-to-pgp --run "ssh-to-pgp -i /etc/ssh/ssh_host_rsa_key -o 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.  To edit a file: cd to `/path/to/nix-files/` and run:
    * `nix-shell -p sops --run "sops secrets/secret_file.yml"`
    * New shell alias: `sops secrets/secret_file.yml`
2.  When you add a new machine, you must update the secrets files encryption.  
    * Run `sops-update secrets/secrets.yaml` and commit the change.

# Lanzaboote / SecureBoot
*  Instructions here - [Link](https://git.sysctl.io/Mirrors/lanzaboote/src/branch/master/docs/QUICK_START.md)
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`
