Prepare release notes for next HypriotOS v1.0.0 release "Blackbeard"

[DieterReuter]

HypriotOS 1.0.0-rc1

This is the first major release of HypriotOS for the Raspberry Pi - a Debian-based Container OS focussed on security and minimal size with all the necessary Docker tools already pre-installed. It is heavily inspired by Raspbian and supports absolutely all Raspberry Pi models (1, 2, 3, Zero & Compute Module) out-of-the-box. The Linux kernel is optimised for use of Docker containers and runs on both ARMv6 and ARMv7 CPU's.

From Zero to Docker in five minutes only: Downloading the SD card image, flashing it to a SD card and booting up the Raspberry Pi takes less than five minutes - and the latest Docker Engine is already up and running.

Contents

• Linux Kernel 4.4.15 (optimised for Docker)
  • dual-arch kernel for ARMv6 and ARMv7 (supports all Raspberry Pi models)
• Docker Engine 1.12.1-rc1 (officially build from Docker)
• Docker Machine 0.8.0
• Docker Compose 1.8.0
• Hypriot Device Init 0.1.8
• Hypriot OS-RootFS 1.0.0-rc1 - Raspbian/Jessie "Raspbian GNU/Linux 8 (jessie)"

  Features

• The root filesystem of the SD card will be automatically resized on first-boot
• No built-in "root" user for increased security
• Only a single standard user (username "pirate", password "hypriot") with sudo rights
  • User "pirate" is member of group "docker", can start docker commands directly
  • User "pirate" is member of group "video", can access the Raspberry Pi camera module
• device-init allows image customisation before first-boot
  • Standard hostname "black-pearl", can be configured in /boot/device-init.yaml
  • WiFi can be configured via device-init in /boot/device-init.yaml
  • Hypriot Flash tool directly supports device-init configuration
• Avahi service discovery built-in
  • find your Pi with a simple ping black-pearl.local or ping black-pearl on the network
• Console login via UART pins is enabled by default (for all Raspberry Pi models including Pi 3)
• almost all WiFi firmware included (atheros, brcm80211, libertas, ralink, realtek) for maximum compatibility
• Using Overlay filesystem for Docker storage-driver is activated by default

  Improvements

• Reduced Image size (1000M/1.0.0-rc1 vs. 1300M/v0.8.4) for quicker SD card flashing
  • flashing to a SanDisk Ultra 16GB microSD card takes 01:56min only (2014 MBP, OS X 10.11)
• Reduced .img.zip size (252M/1.0.0-rc1 vs. 504M/v0.8.4) for smaller and faster downloads
• Optimised filesystem to support more I-nodes (1x I-node per 4kByte block)
• Faster boot times (measured with a freshly flashed SD card, no containers, no additional apps)
  • first-boot: 21sec from power-on to login prompt on UART console
  • normal boot: 15-17sec from power-on to login prompt on UART console
  • reboot: 22sec to login prompt on UART console
• Minimised memory usage, 46MByte only (new install, right after boot, w/ SSH session)
• Minimised disk usage, 750MByte only (new install)

Removed Features

• Hypriot Cluster Lab (already available as separate .deb package)

  Known Issues

• this release currently only works on Pi 2 & Pi 3 as the Docker Engine 1.12.1-rc1 is built for ARMv7 only (should be fixed with the 1.0.0 release)
