The number refers to a specific issue tracker entry for TrueNAS , the popular open-source storage operating system. Specifically, it is a suggestion to automatically create a snapshot as part of an OS upgrade (NAS-125176).

NAS-125176 Status: Feature Request / Suggestion Platform: TrueNAS SCALE / CORE 🔍 Executive Summary 125176
Removes the human error of forgetting to manual backup before an update.
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 The number refers to a specific issue tracker
TrueNAS already utilizes "Boot Environments," which act similarly to snapshots but require a reboot to switch between different OS versions. 🚀 Recommended Next Steps
