Summary

Release Note

The new headless image will be tailored for an audience that will be determined as part of this Blueprint. What ever the outcome this image is likely to change. Initial thoughts are that the image will be trimmed down in size to become a 'nano' like image, meaning downloading and using the image will be much faster. This smaller image will lend itself to board verification.

"The Linaro team is pleased to announce the availability of the Linaro Nano Image. This image is a evolution of the previous 'headless' image, cutting down the number of packages by XXX and reducing the size by YYYY. This image is intended as a board verification image allowing initial power-up and verification to be done. A command prompt will be reached if the board is fully supported. For a more developer focused image please see the Developer image instead."

Rationale

The current headless image is neither small enough to be used as just a verification platform nor encompassing the right tools to be a developer image. The idea is to split the headless image into two to further differentiate the target audiences.

User stories

John has a new OMAP4 based Panda board and would like to quickly test whether the hardware works. He quickly downloads the small nano image, uses the linaro-media-create tool to create a bootable SD card image, and powers up the board.

Assumptions

  • There is a need for a very small nano image by our target audiences.
  • The headless image is not sufficient for many use cases.
  • The current headless image can be reduced in both package count and size.

Design

  • Reduce the package count and size of the current headless image.
  • Strip down all but the essentials to get to a command prompt.

Implementation

  • A new seed will be created with the minimum amount of packages needed to get to a command prompt. No extra packages will be included.
  • The current headless image will be discontinued in favour of the new nano image and a developer image.

Seed Changes

Seed changes should include an overview of what needs to change, and in some cases even the specific details.

Migration

Migration from the headless image to a new nano image will not be allowed.

Test/Demo Plan

The seed changes will be tested locally by the assignee for the ability to boot to the command prompt and also by the community using qaracker.linaro.org.

Unresolved issues

This should highlight any issues that should be addressed in further specifications, and not problems with the specification itself; since any specification with problems cannot be approved.

BoF agenda and discussion

Use this section to take notes during the BoF; if you keep it in the approved spec, use it for summarising what was discussed and note any options that were rejected.
