I bet ZFS would already be there if not for license compatibility issues.

Why is ZFS/OpenZFS not used by (more) Linux distros?

ben_bai • Apr 19, 2015 • View on HN

ZFS is production ready. Use FreeBSD!

Why not? There's already support for zfs.

Strange there's no mention of FreeBSD's excellent ZFS implementation

Just use ZFS with Linux? It's been available as kernel modules for I don't know how long.

It is more like the ZFS started supporting Linux, not FreeBSD uses Linux implementation.

Probably just due to the licensing issues surrounding zfs and linux.

Linux has ZFS too. FreeBSD actually switched over to using the Linux implementation a few years ago.

It might be due to licensing, even Linux went with btrfs (not sure if they mainlined zfs yet).
