** Description changed: + [Impact] + + * zfs fails reverting to a previous snapshot on reboot when selected on + grub + + * A miss-merge dropped initramfs hook changes, which result in failing + to generate and use a new zfs uid. + + [Test Plan] + + * Create snapshot with $ zsysctl save test-sru --system + + * Reboot and attempt to boot into test-sru snapshot + + + [Where problems could occur] + + * The change is to initramfs hook only, thus initrd generation and boot + paths are affected. Only latest initrd is rebuilt, rather than old ones, + meaning booting initrds of older kernel abis will not be resolved. + + [Other Info] + + * Original bug report + After creating a snapshot with: zsysctl save 211012-linux13-19 -s the reboot fails as shown on the screenshot, the other screenshot shows the result of the snapshot.
