The change worked on my PC. The difference has been tested with limited changes
to my userdata, but I try tomorrow with the next set of updates. The current
snapshots are:

That autosys snapshot has been created automatically the first time I did run
the next script to create a snapshot:
zsysctl save $1 -s
zfs list -t snapshot | grep rpool
zfs list -t snapshot | grep bpool
According to the Internet the next commands would stop all autosys
snapshots
systemctl --user stop zsys-user-savestate.timer
systemctl --user disable zsys-user-savestate.timer
sudo mv /etc/apt/apt.conf.d/90_zsys_system_autosnapshot /etc/apt/apt.conf.d
/90_zsys_system_autosnapshot_disabled
Did I make an error or is it another bug?

Title:
zfs fails reverting to a previous snapshot on reboot when selected on
grub
Status in zfs-linux package in Ubuntu:
Triaged
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.
