I don't know of any way to do it using the official release scripts either.
One problem is that every ZFS pool and file system is supposed to have a
unique GUID.  So any kind of ZFS release builder would need to re-guid the
pool on first boot.

Hi,

Does anyone know how to build ZFS disk images from any existing tooling?

I haven't used UFS for over a decade now and the official cloud images
are all UFS, so I end up doing an install from the CD ISO into Hyper-V
locally and then exporting the VHD, but that can't be the most efficient
way of getting a FreeBSD VHD with ZFS.

I haven't been able to find any documentation and reading the release
scripts they seem to hard-code UFS.
Would poudriere work for you? man poudriere-image

Wow, there's a lot of stuff I didn't know poudriere could do! It looks as if it can produce a GPT partition table with all of the bootable bits, or it can produce a ZFS disk image. I guess it wouldn't be too difficult to teach it to do both?
