We should therefore always install with encryption enabled on zfs systems, with a non-secret key by default, and allow the user to use 'zfs change-key -o keylocation=prompt' after install to take ownership of the encryption and upgrade the security. This is also the simplest way to allow users to avoid having to choose between the security of full-disk encryption, and the advanced filesystem features of zfs since it requires no additional UX work in ubiquity. We should make sure that https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1857040 is fixed first in the kernel so that enabling zfs encryption does not impose an unreasonable performance penalty.
