Title:
zfs fails reverting to a previous snapshot on reboot when selected on
grub
Status in zfs-linux package in Ubuntu:
Fix Released
Status in zfs-linux source package in Impish:
Fix Committed
Bug description:
[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.
* Thus revert code to how it was before in
https://launchpad.net/ubuntu/+source/zfs-linux/2.0.2-1ubuntu3
[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.
