There&#x27;s clearly a continuum between two independent programs distributed on the same DVD through to a pre-linked static binary combining two pieces of code together.<p>I believe the OSI point is aiming towards the first part of that continuum (and of course the GPL itself specifically disclaims &quot;mere aggregation&quot;).  The line here is somewhat fuzzy, but for example if you were selling NAS boxes based on linux-on-ZFS, it seems to me that it would be hard to explain that away as &quot;mere aggregation&quot;, since the essential functionality of the product relies on both those parts working together.
