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.
Fixed small typo, missing "i" in either "After installing the *zfs-release* package and verifying the public key
users can opt to install `either` the DKMS or..."
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.

Refresh the documentation to more clear and to account for changes
for made in the recent RHEL/CentOS releases.
- Replaced most ZFS on Linux references with OpenZFS.
- Condensed the list of repositories and made it clear which repos
are updated with new packages and which had been archived.
- Added separate instructions for RHEL/CentOS 6,7 and for RHEL/CentOS
8 and newer since the package manager was changes from yum to dnf.
- Recommend using `yum-config-manager` or `dnf config-manager` rather
than manually modifing the zfs.repo file.
- Converted the important notices to "notes" and reworded them. The
exact commands in the documention were also for much older versions
of ZFS and were removed entirely. This should be less of an issue
with more modern releases.
- Add a comment explaining the modules are automatically loaded
when a pool is detected, but they can always be loaded at boot
time by creating a /etc/modules-load.d/zfs.conf file.

Refresh the documentation to more clear and to account for changes
for made in the recent Fedora releases.
- Replaced most ZFS on Linux references with OpenZFS.
- Reworded kernel compatibility note and link directly to the
latest supported OpenZFS release to make it easy to check the
maximum supported kernel version.
- Removed the kernel-devel package from the dnf install command.
The pacakge is now correctly brought in as a dkms dependency.

- Renamed the page to "Module Parameter" since it now applies
equally to Linux and FreeBSD.
- Updated spl_kmem_cache_expire, spl_kmem_cache_obj_per_slab_min,
spl_kmem_cache_kmem_limit to note the last version they were
included in.
- Added new l2arc_mfuonly, l2arc_rebuild_blocks_min_l2size,
l2arc_rebuild_enabled, and l2arc_trim_ahead options which
were added in OpenZFS 2.0 for the persistent L2ARC feature.
