On a fresh and up-to-date Ubuntu 20.04 amd64 installation I configured
two encrypted partitions on the same hdd. On these I created a stripped
zpool. After login I can import and mount the pool without problems, but
the at-boot import fails after the first partitions is available and
never tried again.
zpool version:
zfs-0.8.3-1ubuntu12.2
zfs-kmod-0.8.3-1ubuntu12.2
