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.

This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like: We need to review the default selection criteria for new options. We need to review any new options to ensure they are sensibly set. Finally we need to review important options such as filesystem selections and security options to ensure they are set as expected.

Summary

Review of the kernel configuration for Oneiric. This will concentrate on confirming the policy for various option type, as well as new options. For major new options, discussion and confirmation of the selection of each.

Release Note

TBD

Rationale

We need to review the Oneiric kernel config to:

  • Ensure sanity of options we have enabled/disabled
  • Ensure that we have the best possible coverage for hardware
  • Ensure we maintain our security options

Implementation

We need to review the default selection criteria for new options. We need to review any new options to ensure they are sensibly set. Finally we need to review important options such as filesystem selections and security options to ensure they are set as expected.

Selection Criteria

The basic rules are:

  1. if the option may be selected as module then we will enable it as a module,
  2. if the option creates a new subsystem (or filesystem) we will enable it,
  3. if the option is unlikely to cause regressions to existing behaviour we will enable it,
  4. if the option is dependent on EXPERIMENTAL then our normal policy is to not enable it,
  5. else it will be disabled.

Additionally we have general policy of building in:

  1. subsystems associated with busses (as they will probe much earlier that way)
  2. boot essential subsystems
  3. default filesystems
  4. extremely common drivers
  5. usbhost interface drivers as they have huge ordering requirements
  6. cpufreq because it's hard to do in userspace
  7. non-discoverable drivers
