Comes in binary form from Debian and Ubuntu. I can add it to any other distribution via DKMS. Same core ZFS code as BSD uses.

Honest question - if it comes in binary form, how can you know it's the same core ZFS code BSD uses?

Same as anything else installed as a binary package - you trust the people packaging/providing the binary. If you don't, build it yourself. The source is publicly available.

Or you build it yourself and verify you got the same checksum.

Debian only distributes it in DKMS form, not binary form.
