Did try without success: d-i partman-auto/disk string /dev/zvol/zd0 d-i partman-auto/method string regular d-i partman-auto/choose_recipe select atomic d-i partman-partitioning/confirm_write_new_label boolean true d-i partman/choose_partition select finish d-i partman/confirm boolean true d-i partman/confirm_nooverwrite boolean true
To install zfs should try: d-i pkgsel/include string zfs-initramfs
Action at end: Continue Testing
Selection, partitioning, and formatting of the zvol within the Ubiquity installer may be automated and skipped.
