feat: Complete sleeper-service deployment with ZFS and network fixes

✅ Major deployment milestone achieved:

**sleeper-service Configuration:**
- Successfully deployed flake-based NixOS on Intel Xeon file server
- Resolved ZFS mounting conflicts causing boot failures
- Implemented ZFS native mounting (/mnt/storage, /mnt/storage/media)
- Added Pi-hole DNS integration (10.0.0.14) for package resolution
- Configured systemd-networkd with static IP (10.0.0.8)
- System boots cleanly in ~1 minute with ZFS auto-mounting

**Infrastructure Updates:**
- SSH key management deployed and operational
- Network configuration with multi-tier DNS (Pi-hole, router, Google)
- NFS server configuration for network storage
- Data preservation verified: 903GB ZFS pool intact

**Technical Solutions:**
- Added nomodeset kernel parameter for graphics compatibility
- Disabled NVIDIA drivers for headless server operation
- Removed conflicting ZFS entries from hardware-configuration.nix
- Established remote deployment workflow via rsync + SSH

**Documentation:**
- Updated plan.md with deployment status and lessons learned
- Added deployment commands and troubleshooting notes
- Documented ZFS native mounting migration process

**Data Verified:**
- Films: 184GB, Series: 612GB, Audiobooks: 94GB, Music: 9.1GB, Books: 3.5GB
- Storage pool: 903GB used, 896GB available
- All media accessible via proper ZFS auto-mounting

This represents the first successful multi-machine flake deployment in the home lab infrastructure migration.

+## Deployment Status & Accomplishments ✅
+
+### sleeper-service Deployment (COMPLETED)
+**Date**: Recently completed  
+**Status**: ✅ Fully operational  
+**Machine**: Intel Xeon E3-1230 V2, 16GB RAM (formerly files.home)
+
+#### Key Achievements:
+- **Flake Migration**: Successfully deployed NixOS flake configuration on remote machine
+- **ZFS Stability**: Resolved ZFS mounting conflicts causing boot failures
+- **Data Preservation**: All 903GB of media data intact and accessible
+- **Network Integration**: Added Pi-hole DNS (10.0.0.14) for package resolution
+- **SSH Infrastructure**: Implemented centralized SSH key management
+- **Boot Performance**: Clean boot in ~1 minute with ZFS auto-mounting enabled
+- **Remote Deployment**: Established rsync + SSH deployment workflow
+
+#### Technical Solutions:
+- **ZFS Native Mounting**: Migrated from legacy mountpoints to ZFS native paths
+- **Hardware Configuration**: Removed conflicting ZFS filesystem entries
+- **Graphics Compatibility**: Added `nomodeset` kernel parameter, disabled NVIDIA drivers
+- **DNS Configuration**: Multi-tier DNS with Pi-hole primary, router and Google fallback
+- **Deployment Method**: Remote deployment via rsync + SSH instead of direct nixos-rebuild
+
+#### Data Verified:
+- **Storage Pool**: 903GB used, 896GB available
+- **Media Content**: Films (184GB), Series (612GB), Audiobooks (94GB), Music (9.1GB), Books (3.5GB)
+- **Mount Points**: `/mnt/storage` and `/mnt/storage/media` with proper ZFS auto-mounting
+
+#### Next Steps for sleeper-service:
+- [ ] Implement automated backup services
+- [ ] Add system monitoring and alerting
+- [ ] Configure additional NFS exports as needed
+- [ ] Plan storage expansion strategy
+
+#### Lessons Learned:
+1. **ZFS Mounting Strategy**: Native ZFS mountpoints are more reliable than legacy mounts in NixOS
+2. **Remote Deployment**: rsync + SSH approach avoids local machine conflicts during deployment
+3. **DNS Configuration**: Manual DNS configuration crucial during initial deployment phase
+4. **Graphics Compatibility**: `nomodeset` parameter essential for headless server deployment
+5. **Boot Troubleshooting**: ZFS auto-mounting conflicts can be resolved by removing hardware-configuration.nix ZFS entries
+6. **Data Migration**: ZFS dataset property changes can be done safely without data loss
+7. **Network Integration**: Pi-hole DNS integration significantly improves package resolution reliability
