Related: I moved to a new laptop at work with a zfs send over ssh of /home/myuser - and a mount+manual copy of what I wanted. Very straight forward - but not that different from an rsync to /home/myuser/olfstuff.

Zfs encryption was still a bit new, so both boxes uses dmcrypt on full disk plus efi plus /boot (technically redundant, but it works).

Looking forward to hopefully root on encrypted zfs in next Ubuntu lts.
