The yes-no-yes-no saga concerning ZFS in Leopard continues as Apple has released a new statement concerning the availability of ZFS in Leopard. So, let’s recap: in April 2006, Apple expresses its interest in Sun’s ZFS for the first time. After a first hint, the first screenshot popped up which showed ZFS on Leopard, followed by the definitive proof Leopard could create ZFS disk images. Fast forward six months, and Sun’s Jonathan Schwartz announces that ZFS would be Leopard’s default filesystem; a statement contradicted by an Apple official yesterday. In fact, this Apple official said ZFS would not be in Leopard at all. Then we arrive at today, and we have Apple stating that ZFS will in fact be included as a limited option in Leopard, only from the command line, read-only. Let’s see what tomorrow will bring.
