Comment 4 for bug 1782744

The boot environment does not include the zfslinux-utils package.

Has that changed?

Command: ['zpool', 'list', '-H', '-o', 'name']
Reason: [Errno 2] No such file or directory: 'zpool': 'zpool'

I don't think this is a dupe of that; there was an issue with other zfs pools being activated which curtin now will remove/disable. But to do so it using zfs tools to query the system state.

Can you dpkg query system to see if any zfs packages are installed?

The live image needs to have zfslinux-utils package, or invoke curtin with --install-deps (which will check and apt install as needed).
