|
| |
| == Detailed Description ==
| |
| Currently in kexec-tools we use our own /sbin/mkdumprd to generate an initrd for kdump kernel. However, due to the natural complexity of making a new initrd, we have lots of burdens to maintain the mkdumprd code, we decide to switch to using dracut to generate kdump initrd. And hopefully, we can provide a distro-independent mkdumprd to upstream, as dracut itself is cross-distribution.
| |
|
| |
| == Benefit to Fedora ==
| |
| The main source of kexec-tools bugs is in mkdumprd, with this change, hopefully we will reduce the number of bugs of kexec-tools.
| |
|
| |
| == Scope ==
| |
| All functionality of /sbin/mkdumprd has to be implemented and tested in this new mkdumprd.
| |
|
| |
| == How To Test ==
| |
| <!-- This does not need to be a full-fledged document. Describe the dimensions of tests that this feature is expected to pass when it is done. If it needs to be tested with different hardware or software configurations, indicate them. The more specific you can be, the better the community testing can be.
| |
|
| |
| Remember that you are writing this how to for interested testers to use to check out your feature - documenting what you do for testing is OK, but it's much better to document what *I* can do to test your feature.
| |
|
| |
| A good "how to test" should answer these four questions:
| |
|
| |
| 0. What special hardware / data / etc. is needed (if any)?
| |
| 1. How do I prepare my system to test this feature? What packages
| |
| need to be installed, config files edited, etc.?
| |
| 2. What specific actions do I perform to check that the feature is
| |
| working like it's supposed to?
| |
| 3. What are the expected results of those actions?

| == User Experience ==
| |
| <!-- If this feature is noticeable by its target audience, how will their experiences change as a result? Describe what they will see or notice. -->
| |
|
| |
| == Dependencies ==
| |
| Dracut
| |
|
| |
| == Contingency Plan ==
| |
| <!-- If you cannot complete your feature by the final development freeze, what is the backup plan? This might be as simple as "None necessary, revert to previous release behaviour." Or it might not. If you feature is not completed in time we want to assure others that other parts of Fedora will not be in jeopardy. -->
| |
|
| |
| == Documentation ==
| |
| <!-- Is there upstream documentation on this feature, or notes you have written yourself? Link to that material here so other interested developers can get involved. -->
| |
| * Not applicable, because we don't have documentations for this replacement.
| |
|
| |
| == Release Notes ==
| |
| <!-- The Fedora Release Notes inform end-users about what is new in the release. Examples of past release notes are here: http://docs.fedoraproject.org/release-notes/ -->
| |
| <!-- The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns. If there are any such changes involved in this feature, indicate them here. You can also link to upstream documentation if it satisfies this need. This information forms the basis of the release notes edited by the documentation team and shipped with the release. -->
