This is a snapshot of an experimental OmniOS aarch64 distribution that can be
booted under QEMU or on a Raspberry Pi 4.

It based on the arm64-gate project at https://github.com/richlowe/arm64-gate
and OmniOS userland packages from https://github.com/omniosorg/omnios-build
and https://github.com/omniosorg/omnios-extra

The sample 'run' file here shows how to boot this under qemu using the vnic
backend (present in OmniOS and OpenIndiana's qemu packages).

##############################################################################
## QEMU

Quick start for OmniOS r151044 or higher, assuming that `igb0` is the
system's network interface:

  % pfexec pkg install emulator/qemu
  % mkdir ~/aarch64
  % cd ~/aarch64
  % curl -LO https://downloads.omnios.org/media/braich/braich-151051.raw.zst
  % curl -LO https://downloads.omnios.org/media/braich/inetboot.bin
  % curl -LO https://downloads.omnios.org/media/braich/u-boot.bin
  % curl -LO https://downloads.omnios.org/media/braich/run
  % zstd -d braich-151051.raw.zst
  % pfexec dladm create-vnic -l igb0 braich0
  % ./run

## OmniOS "emu" zone

On OmniOS, you can also use `zadm` to create an emu-branded zone to run this.
First use `zadm list-images -b emu` to show available options:

  # zadm list-images -b emu
  UUID      PROVIDER  BRAND   NAME                                VERSION
  af844464  omnios    emu     omnios-aarch64-braich               bloody
  41232cad  omnios-us emu     omnios-aarch64-braich               bloody

Then with the UUID of the image you wish to use (the two above only differ in
where they will be downloaded from):

  # zadm create -b emu -i <image UUID> <zone name>

If you're happy with all of the default settings that appear in the
editor, save and quit, otherwise adjust as desired.

Once installation completes, boot the zone and attach to the console:

  # zadm boot -c <zone name>

## Raspberry Pi 4

For running on a Raspberry Pi, download and decompress

  https://downloads.omnios.org/media/braich/braich-rpi4-151051.raw.zst

and write it to an SD card. If you experience any issues, ensure that the
pi's bootloader is up to date.
