Encourages users to keep their systems updated with the latest security patches, knowing they have a fallback. 🛠️ Current Status & Workarounds ✨ Key Benefits Until this is fully integrated
Since you asked for a "report" on this topic, I have prepared a summary of this feature request and its importance for system administrators. 📋 Feature Report: NAS-125176 Automatic Snapshots During OS Upgrades moving from Bluefin to Dragonfish)
This request proposes a safety mechanism within the TrueNAS update utility. Before a system applies a major operating system upgrade (e.g., moving from Bluefin to Dragonfish), it would automatically trigger a ZFS snapshot of the boot pool. This ensures that if the new update fails or causes hardware incompatibility, the user can instantly roll back to a known-working state. ✨ Key Benefits
Until this is fully integrated as a "toggle" in the UI, include a Boot Pool Snapshot as a standard step in your maintenance checklist.
