The convention here is to add a blank line between commands that
cannot be copied-and-pasted together. apt is such a command, as it
will eat the input from the paste.
It is not necessary to enable universe in the Live CD. zfs-initramfs is
in main these days.
I left universe (and multiverse) enabled in the installed system.
People who care can customize.
In general apt is the preferred way to interact with packages, and I
think in this case there is no need/advantage to use dpkg.

[Fixed the other two instances too.]
For a mirror or raidz topology, /boot/grub is on a separate dataset.
This was originally bpool/grub, then changed on 2020-05-30 to
bpool/BOOT/ubuntu_UUID/grub to work-around zsys setting canmount=off
which would result in /boot/grub not mounting. This work-around lead
to issues with snapshot restores. The underlying zsys issue
ubuntu/zsys#164 was fixed and backported to 20.04, so it is now back to
being bpool/grub.
This reverts commit b6fd009edd. It
conceptually reverts the errata notes from commit
04d3c1cee4, but includes new steps for
people in the pre-2020-05-30 state.

I think (but am not absolutely certain) that things behave as follows:
- The non-zsys initramfs script expects canmount=noauto for the root
filesystem. It then mounts the active one (e.g. in the case of
clones) manually, overriding that.
- zsys manages the canmount attribute.
I am sure that when the system boots with zsys, the initial datasets,
which were created with canmount=noauto, have canmount=on.
Therefore, there seems to be no reason to set canmount=noauto for the
zsys scenario, and I have removed it. This simplifies the instructions
and may avoid issues like #73.

Ubuntu 20.04's GRUB supports multiple EFI disks. There is a small
caveat in that it doesn't prompt in the chroot, but it works fine after
the reboot. Using the stock support means that the ESPs will be kept in
sync automatically.

This is how the Ubuntu 20.04 installer configures the ESP to mount at
/boot/efi, so it should be fine to use this convention everywhere.
/dev/md0's /dev/disk/by-uuid entry does not show up immediately, so I
removed the swapon there.

On Ubuntu, console-setup, keyboard-configuration (a dependency of
console-setup), and locales are installed by default. On Debian, we
need to install them manually. (We were already doing so for locales.)
I merged the various dpkg-reconfigure lines into one to simplify. The
order isn't important.

The docs note that I tested this, but I'm going to remove this, out of
an abundance of caution given the report of failure in #57. I may re-test
later, but this isn't a huge priority for me.
Fixes#57
If the user gives too short of a password when encryption via a hacked
installer, the installer will crash. (I haven't personally verified
this, but it sounds plausible.)

Closes: 52
The open-zfs.org host, Dreamhost, returns a page for https://open-zfs.org
(note, httpS://) which causes HTTPS Everywhere with the 'Encrypt All
Eligible Sites' option enabled to redirect http://open-zfs.org to
https://open-zfs.org, and therefore fail to redirect to openzfs.org.
Ideally a redirect would be implemented at Dreamhost for
httpS://open-zfs.org too, but presumably the links in the docs should
really be updated anyway.
zsys was setting canmount=off on bpool/grub. It is now
bpool/BOOT/ubuntu_UUID/grub.

This is the service for /boot/grub/grubenv which does not work on
mirrored or raidz topologies. Disabling this keeps it from blocking
subsequent mounts of /boot/grub if that mount ever fails.

This now mentions that the user might want to customize the swap size.
It also specifically mentions hibernation and the requirement to size
the swap at least as large as the system RAM.
Note: I have not tested hibernation.
