Whoa - that is a pretty big item. Thanks for mentioning that. One of my todos this year is to check out encrypted ZFS on Linux. I will try that on Void.
I've been running encrypted ZFS on Void for about a year. [Only caveat: I wasn't able to get an encrypted ZFS root working on Void (there is some issue with grub+luks+zfs), but I have system with an unencrypted ZFS root with an encrypted /home on ZFS.]
