The CDDL is as incompatible to the GPL as the BSD license. |

Both do not allow to change the license of the code and for this reason, a code |
| 21 |
combination cannot happen as a "derivative work". If you like to create a |
| 22 |
derivative work from a GPL program and BSD code from another person, you would |
| 23 |
need to declare the code from another person to be _your_ "modification". This |
| 24 |
is something that would violate the Copyright law. |
| 25 |
|
| 26 |
The GPL however permits code combinations as "collective work". As the GPL |
| 27 |
then is only valir for the GPL part of the whole, this does not cause |
| 28 |
"incompatibilities". |

In 2002, the ZFS developers have already been forced to have their |
| 43 |
homedirectories on ZFS. In 2004, ZFS was already under test in universities. |
