I just learned that it was part of 0.7.0 and the ArchWiki explains its usage: https://wiki.archlinux.org/index.php/ZFS#Native_encryption I did not find any flag to enable it in the current source, so you're right. It's there in GIT, yet not merged with the release itself. That was my impression before reading in the Wiki as well. > it will most likely be part of 0.8, and if that gets cut in time for PVE > 6 we will surely take a closer look again when we start preparing for > that. Looking forward to it. Hopefully, other features from illumos will also be part of 0.8 like vdev shrinkage etc. > do you have specific use cases in mind?

Yes, that'll going to be hard. LUKS is better at this with preboot authentication and stuff like that. > (I do use ZoL on top of LUKS as / on a few systems without any problems, > but it requires manually bootstrapping the system and a bit of fiddling > to get all the parts to play nice with eachother ;)) Yes, I'm using ZFS on top of LUKS already, yet an "internal" solution could be better. The workflow as described in the ArchLinux Wiki is not that easy in practise as someone would want. It is basically the same as LUKS, which is proven to work marvelously.
