Deployment Failure with Snapper Error

The deployment process halts when encountering the specific error string 'Could not mount Btrfs subvolume '/@/snapshots' on openSUSE.

Snapper Snapshot Handling

This failure points directly to the snapper component's inability to manage Btrfs subvolume snapshots during the installation phase.

Given the version dependency in openSUSE Leap 15.5 regarding the 'ROLLBACK_ON_TRANSACTION_FAILURE' option, what is the definitive mechanism for system state recovery after this specific snapshot mounting failure?

Does the system guarantee a bootable state even if the automatic rollback is not explicitly triggered by snapper?
What is the required verification method to confirm the integrity of the pre-failure system state without relying solely on log parsing?

Snapper snapshot missing after zypper transaction

Unclear whether openSUSE Snapper snapshots after zypper transactions or only on systemd timer, and how to test without production credentials.

Does Snapper rollback verify integrity of restored system files against the original snapshot checksums?

Snapper rollback replaces system files from a Btrfs snapshot but does not document whether it verifies restored content against stored checksums. This leaves a gap when recovering from potential silent corruption.

Btrfs snapshot retention configuration on OpenSUSE minimal-install servers

OpenSUSE's default Btrfs snapshot auto-creation can lead to unbounded disk usage on low-traffic servers if retention is not configured. The trade-off between convenience and storage cost becomes critical for cost-sensitive deployments.

Snapper space-aware cleanup on openSUSE: enable qgroups or keep quotas off?

openSUSE's Snapper can prune snapshots by real disk usage only with Btrfs qgroups enabled — a trade-off between accurate accounting and documented performance cost.
