** Description changed: This issue seems similar to 1894329 but I can reproduce this consistently in 21.10. Problem description: Unable to reliably revert ZFS snapshots via the Grub menu in Ubuntu 21.10. When attempting a revert I am usually dropped to the emergency mode and have to force a reboot. After that it can take a number of attempts to get the system to reboot to the desktop. Steps to reproduce: Install Ubuntu 21.10 on Intel 64bit with ZFS selected as the filesystem. Do not encrypt. Install all updates. ZFS snapshot is taken automatically. Reboot. Install a simple package i.e. sudo apt install neofetch. Another ZFS snapshot is taken automatically. Reboot and enter the GRUB menu. Enter History menu. - Select Revert to an earlier snapshot. In my case I select the snapshot taken after neofetch was installed. + Select Revert to an earlier snapshot. In my case I select the snapshot taken before neofetch was installed. Select install system files only. Do not select the recovery mode option. System now boots and ends up dropping into emergency mode. I can duplicate this on three different installs. - Expected outcome: The snapshot is correctly reverted and the system boots without user interaction into the snapshot.
