I believe so. The package descriptions for most of the ZFS packages in Ubuntu mention OpenZFS, so it certainly appears that way.

You can still create pools that are compatible with Oracle Solaris, you just have to set the pool version to 28 or older when you create it and obviously don’t update it. That will prevent you from using any of the newer features that have been added since the fork.

Well worse than that, Oracle closed sourced ZFS, so OpenZFS was forced to become a fork, and they are no longer compatible with each other.

As for GPL the CDDL license that ZFS uses made sure that code contributions attribute copyright to the project owners, which means they can change the license as they please without having to track down contributors.

You would think with their investments in Oracle Linux and btrfs they would welcome that license change, but apparently they need excuses to keep putting money into Solaris, and their Oracle ZFS appliances instead.

Digitizer issues are usually from getting the wrong digitizer. They are programmed differently for the HAC-001(-01) (v2 classic switch) vs the HAC-001 (v1 classic switch).

More specifically the game card reader board that the digitizer plugs into needs to match. So make sure you buy your digitizer to match the game card reader version, or buy a game card reader to go with it (you can get them for ~$14). Unfortunately many digitizer sellers on eBay don’t say which model it is designed for.

Alternatively you can mix and match those versions if you have an unpatched/modded switch. Just launch Hekate, go to tools and run the digitizer calibration.

I haven’t repaired too many switches but the first time it happened to me I had a spare v2 game card reader and that fixed it immediately. Second time I used the Hekate method and that worked just as well
