[pve-devel] [RFC v2 storage 06/10] zfs pool plugin: implement method to get qemu blockdevice options

[Fiona Ebner]

ZFS does not have a filesystem_path() method, so the default
implementation for qemu_blockdev_options() cannot be re-used. This is
most likely, because snapshots are currently not directly accessible
via a filesystem path in the Proxmox VE storage layer.

New in v2.
