Reassigning to zsys, but also closing tentatively as opinion, as the snapshot has not been made using zsys, so this seems like it is out of scope.
** Package changed: grub2 (Ubuntu) => zsys (Ubuntu) ** Changed in: zsys (Ubuntu) Status: New => Opinion -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to zsys in Ubuntu. https://bugs.launchpad.net/bugs/1949490 Title: Grub doesn’t fully revert ZFS snapshots Status in zsys package in Ubuntu: Opinion Bug description: To reproduce this bug, take the following steps Install Ubuntu 20.04.3 using a ZFS-based root. Boot into it and get past the initial startup screens. Take a manual recursive zfs snapshot like so zfs snapshot -r rpool@beforeanything Now touch a file on the desktop and install a package like htop. You should see the file and htop should be able to run. Reboot and hit escape to enter the grub screen. Choose the history menu and choose the snapshot you just created. Then hit enter and then choose the option to revert system and user data and then enter again. If it were working correctly, everything should be reverted. There’d be no file on the desktop and no trace of htop. That’s not what occurs. The file on the desktop is still there, and while htop is no longer installed, the package management seems to think it is.
