Release Note

This section should include a paragraph describing the end-user impact of this change. It is meant to be included in the release notes of the first release in which it is implemented. (Not all of these will actually be included in the release notes, at the release manager's discretion; but writing them is a useful exercise.)

It is mandatory.


User stories


  • There are mutually-incompatible requirements for our headless images: some users want an image that is as small as possible with a basic shell environment, some users want a GUIless image that includes a rich set of developer tools (profiling, debugging, compiling?, etc) for kernel and plumbing development.
  • The size of gdbserver is negligible; we should include it on *all* images except for those with specific size constraints (headless, alip)


  • Create a new ARM-targeted "developer" image, while keeping the existing minimal "headless" image
  • Make the developer image a strict superset of the headless image, to reduce maintenance
  • Include developer tools in the developer image:
    • gcc
    • gdb, gdbserver
    • lttng
    • oprofile
    • ltrace
    • strace
    • systemtap
    • input-utils
    • iotop
    • gator.ko, gatord
      • gatord is closed-source
    • powerdebug
    • perf tools (part of kernel package)
    • evtest - maybe input-utils already does this?
    • devmem2
    • i2c-tools
    • abrek
    • usb-utils
    • powertop
    • lsof
  • Drop packages from the headless image that should be moved to the developer image instead - we may do this even for packages that are not developer-oriented, but that we can do without in the minimal image as long as the developer image doesn't get too big
    • ??
    • ??
  • Impose an upper limit on the reasonable size of the developer image - what is this limit?
  • Include other useful packages in the developer image that aren't strictly developer-oriented, but are generally interesting/useful
    • an ssh server?


Seed Changes

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


Because most headless images will not be upgraded in place, we will not try to produce an automatic migration path. Users of the existing headless image who want to pull in the developer tools will be able to do so with an 'apt-get install' of the new developer tools metapackage.

Test/Demo Plan

It's important that we are able to test new features, and demonstrate them to users. Use this section to describe a short plan that anybody can follow that demonstrates the feature is working. This can then be used during testing, and to show off after release. Please add an entry to for tracking test coverage.

This need not be added or completed until the specification is nearing beta.

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.

Outcome of discussions

In Jan 2011 a call for discussions was sent out to the linaro-dev mailing list and all tech leads. No objections or additional packages were requested so the list captured above will be the basis for the developer tools offered this cycle.
