- Remove /mnt/storage/media from systemd.tmpfiles.rules (it's a ZFS dataset mount point)
- Add ExecStartPost to set proper permissions on ZFS-mounted media directory
- Update NFS research documentation with ZFS integration best practices
- Add section explaining ZFS mount point vs tmpfiles.rules conflicts
This resolves the potential conflict where tmpfiles tries to create a directory
that ZFS wants to use as a mount point for the storage/media dataset.
- Create shared media-group.nix module with fixed GID (993)
- Add both geir and sma users to media group for shared NFS access
- Update NFS server configuration to use root:media ownership with 0775 permissions
- Convert all media services to use media group instead of users group:
- Jellyfin, Calibre-web, Audiobookshelf, Transmission
- Enable group write access to all NFS shares (/mnt/storage/*)
- Maintain security with root ownership while allowing group collaboration
This resolves NFS permission issues by providing consistent group-based access
control across all media services and storage directories.
- Consolidated 25+ common CLI tools into modules/common/base.nix
- Added modern rust-based tools (eza, bat, ripgrep, etc.) system-wide
- Removed duplicated packages from user and machine configs
- Added consistent shell aliases for modern CLI tools
- Fixed gpa alias to properly push to all remotes

Benefits:
- Single source of truth for common CLI tools
- Reduced duplication across 7+ configuration files
- Improved git workflow with flexible multi-remote pushing
- Better maintainability and consistency

- Updated sleeper-service configuration with NFS and Transmission
- Fixed SSH key management to use direct key configuration
- Updated hardware-configuration to use sleeper-service hostname
- Added firewall ports for Transmission RPC (9091)
- Add modules/security/ssh-keys.nix for centralized SSH key management
- Generate role-specific SSH keys with geir@geokkjer.eu email:
- Admin key (geir@geokkjer.eu-admin) for sma user server access
- Development key (geir@geokkjer.eu-dev) for geir user and git services
- Update SSH client config with role-based host patterns
- Configure users/geir.nix and users/sma.nix with appropriate key access
- Add SSH key setup to both machine configurations

- Update plan.md with completed SSH security implementation
Security benefits:
- Principle of least privilege (separate admin vs dev access)
- Limited blast radius if keys are compromised
- Clear usage patterns: ssh admin-sleeper vs ssh geir@sleeper-service.home
- Maintains compatibility with existing services during transition
- Fix typo in nix-store alias
