Although I've been using Ubuntu since 2006, I'm new to ZFS & encryption...
I'm playing with a proof of concept VM that has been loaded up with Ubuntu 2104. During the installation, when going through the partitioning screens, I selected the option to set up the drive with ZFS and encryption. My goal was to see whether or not I could recover files from an encrypted ZFS system via an Ubuntu Live environment.
I can boot the test system but I cannot seem to figure out how to access the test data on the system. I've dealt with encryption on Ubuntu before but, Nautilus asked for the passphrase and I was off to the races. In this case, I think I'm missing a step or a package within the live environment because I don't see the typical prompt for passphrase.
