Notes:

Research topics

• Look into this for rotating sops keys https://technotim.live/posts/rotate-sops-encryption-keys/
• Look into this for openssh known configurations https://search.nixos.org/options?channel=unstable&from=0&size=15&sort=alpha_asc&type=packages&query=services.openssh
• Look into this for flake templates https://nix.dev/manual/nix/2.22/command-ref/new-cli/nix3-flake-init
• Look into this for headscale https://carlosvaz.com/posts/setting-up-headscale-on-nixos/
• Look into this for home assistant configuration https://nixos.wiki/wiki/Home_Assistant https://myme.no/posts/2021-11-25-nixos-home-assistant.html

Configuration

set up git configuration for local development: git config --local include.path .gitconfig

to update passwords run: nix shell nixpkgs#sops -c sops secrets/user-passwords.yaml (NOTE: this depends on the SOPS_AGE_KEY_DIRECTORY environment variable being set)

Tasks:

Tech Debt

• vscode extensions should be in own flake (make sure to add the nixpkgs.overlays in it too)
• join config for systemd.tmpfiles.rules and service directory bindings
• monitor configuration in ~/.config/monitors.xml should be sym linked to /run/gdm/.config/monitors.xml
• move applications in server environment into their own flakes

New Features

• offline access for nfs mounts (overlay with rsync might be a good option here? https://www.spinics.net/lists/linux-unionfs/msg07105.html note about nfs4 and overlay fs)
• fix pre commit hook
• Flake templates
• home assistant virtual machine
• searxng docker
• nextcloud ???
• samba mounts
• firefox declarative???
• figure out steam vr things?
• Open GL?
• util functions
• openssh known hosts
• rotate sops encryption keys periodically (and somehow sync between devices?)
• zfs email after scrubbing
• headscale server (just needs to be tested)
• mastodon server
• tail scale clients
• wake on LAN
• ISO target that contains authorized keys for nixos-anywhere
