My machine did not reboot successfully; because I followed The Guide, my system has a root password, and I was prompted for it at the systemd emergency shell. (Which is super-confusing, because I forgot I had set a password.)
The error message appeared to be along the lines of "bpool failed to import because it was most recently used on another machine". (This is a lie; rpool, on the same nvme, didn't say the same thing.) I was able to proceed again after a 'zpool import -f bpool', reboot, and then things seemed to work well.

I've also set up sanoid to perform periodic snapshots of bpool (which stores /boot). The upgrade from disco to eoan didn't go well: [.. trimmed to fit in the comment box; more context in attachment ..] /ubuntu@autosnap_2020-01-24_04:00:05_frequently Found initrd image: initrd.img-5.3.0-29-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:00:05_frequently Found linux image: vmlinuz-5.0.0-39-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:15:05_frequently Found initrd image: initrd.img-5.0.0-39-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:15:05_frequently Found linux image: vmlinuz-5.0.0-40-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:15:05_frequently Found initrd image: initrd.img-5.0.0-40-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:15:05_frequently Found linux image: vmlinuz-5.3.0-29-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:15:05_frequently Found initrd image: initrd.img-5.3.0-29-generic in rpool/ROOT/ubuntu@autosnap_2020-01-24_04:15:05_frequently Adding boot menu entry for EFI firmware configuration done Processing triggers for dbus (1.12.14-1ubuntu2) ...
