Notes:

Research topics

• Look into this for auto rotating sops keys https://technotim.live/posts/rotate-sops-encryption-keys/
• 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/
• https://nixos-and-flakes.thiscute.world/

Tasks:

Tech Debt

• monitor configuration in ~/.config/monitors.xml should be sym linked to /run/gdm/.config/monitors.xml (https://www.reddit.com/r/NixOS/comments/u09cz9/home_manager_create_my_own_symlinks_automatically/)
• syncthing password

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)
• Flake templates - we need to add these to some kind of local registry??? nix flake show templates - https://nix.dev/manual/nix/2.18/command-ref/new-cli/nix3-flake-init
• samba mounts
• figure out steam vr things?
• Open GL?
• rotate sops encryption keys periodically (and somehow sync between devices?)
• zfs email after scrubbing
• tail scale clients
• wake on LAN for updates
• ISO target that contains authorized keys for nixos-anywhere 4acc43ebc7/hosts/bootstrap/default.nix
• Immich
• zfs encryption FIDO2 2fa
