About ZFS >V.28

Currently, ZFS encryption is Oracle Solaris 11 and ZFS V.31+ only, so if you need, you have no options. But you loose compatibility forever with all other ZFS implementations like FreeBSD, Illumos based ones (Illumian, OpenIndiana, SmartOS), Linux or OSX which are on ZFS V.28

I do not expect newer Versions than V28 that are Oracle compatible.
Its more likely that we see features flags in future, not Versions > 28 from others than Oracle.

Hmm. Feature flags look pretty useful - that's a very interesting PDF.

I didn't see that. Great to know gea!

Main Problem: If you use a feature you loose compatibility with those not supporting the feature.

But I suppose, a pool V. 1000 with features is the only way to add new features in a world where
Oracle can no longer dominate the future without opening ZFS development and a lot of enterprises with
the need to implement new features.

But I hope for a common feature-set. All of the free ZFS developments is or can be concentrated at Illumos.
So I would say, this can be a problem but its more of a good news.
