Cloud-init can't growpart in FreeBSD 14.0 with ZFS #7

[oneumyvakin]

There is a VM with scsi disk driver and 50G disk, but after vm creation / part is not grow:

Not sure what to do to grow / part.

There is no such issue with UFS.

Ah, you don't use the virtio driver? This seems to be the problem. Can you adjust that?

The problem comes from this line: https://github.com/virt-lightning/freebsd-cloud-images/blob/master/build.sh#L125

For some reason I had to hard code the partition, but I'm not sure if we still need that. Overall, it's a cloud-init problem or misconfiguration.
