 - Borg backups need passphrase at `/etc/borg-passphrase`
-- Cookie files for yt-dlp in `config/yt-dlp/`
-- Claude Code permissions configured globally in module
 - Container definitions use podman backend
 - WireGuard configs need manual key exchange after first deploy
-- ZFS snapshots managed by sanoid (where configured)
 - Traefik handles SSL via Cloudflare DNS challenge
 
-## Troubleshooting
-
-```bash
-# Check nix daemon
-sudo launchctl list | grep nix  # macOS
-systemctl status nix-daemon      # NixOS
-
-# Fix store permissions
-sudo chown -R root:nixbld /nix/store
-
-# Rebuild with verbose output
-nixos-rebuild switch --flake .#<host> --show-trace
