ZFS file system/ partitions on debian bullseye with zfs-2.0.3-9

Hello,

pyparted is not recognizing ZFS file system/ partitions on debian bullseye with zfs-2.0.3-9.

Ways to reproduce (simplest example): zpool create pybenchpoolnvm0n1 /dev/nvme0n1

The zpool is mounted and fully accesible

Using the example dump_partitions.py-> changing line 28 to device="/dev/nvme0n1" gives the following output:

***** sanity check *****
result: True
===== device ====
  model: Micron_9300_MTFDHAL3T8TDP

fdisk gives the following output:

blkid gives the following output

/dev/nvme0n1p1: LABEL="pybenchpoolnvme0n1" UUID="787063089205607908" UUID_SUB="12848811619258076980" BLOCK_SIZE="4096" TYPE="zfs_member" PARTLABEL="zfs-9eb193c6297790f1" PARTUUID="20e69604-c1d5-9342-9557-e89f0bde6216"
/dev/nvme0n1p9: PARTUUID="d096a433-516d-be47-b2db-114512132925"

As parted gives the same output than dump_partitions.py example, I have the feeling this has something to do with parted/libparted and or zfs on linux. I'm not sure if I'm doing something wrong or impossible here. So any help is highly appreciated!

Thanks! Chris
