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.) None.

== Implementation ==
Line 28: Line 42:
This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:

=== UI Changes ===

Should cover changes required to the UI, or specific UI that is required to implement this

=== Code Changes ===

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

=== Migration ===

Include:
 * data migration, if any
 * redirects from old URLs to new ones, if any
 * how users will be pointed to the new way of doing things, if necessary.

== 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 http://testcases.qa.ubuntu.com/Coverage/NewFeatures 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.

Line 57: Line 46:
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.  * Kernel Version

 * optimal HZ per flavour

Summary

Discuss the mainline baseline version for Natty. Also discuss the current kernel flavours for each architecture. Discuss the current settings of HZ for each flavour.

Release Note

None.

Kernel Version

Discussions on which mainline kernel base is appropriate for Natty. As Natty is not an LTS we do not require a specific version for alignment upstream. Therefore we will be using the latest version released at kernel freeze.
