Detailed Description

Feedback

Benefit to Fedora

Scope

  • Other developers: No work from other developers will be needed.
  • Policies and guidelines: N/A (not needed for this Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with the Fedora Strategy:

Upgrade/compatibility impact

This change will affect only new installation, no change to the partition table will be done during upgrade.

Early Testing (Optional)

Do you require 'QA Blueprint' support? N

Early testing can be done by using the boot option inst.disklabel=gpt.

How To Test

Any of the installer test cases (for example QA:Testcase_Anaconda_autopart_(use_all_space)_install) can be used to test this. The expected result is that GPT will be used as partition table type on s390x and ppc64le. sudo fdisk -l /dev/sdx can be used to verify.

User Experience

Users shouldn't notice any significant change other than the switch from MSDOS to GPT disklabel. Other than that the user experience during installation, booting or using the system shouldn't change at all.

Dependencies

There are no dependencies for this change, all work will be done in Blivet, the library that Anaconda uses for storage configuration.


Contingency Plan

  • Contingency mechanism: Revert the change in upstream
  • Contingency deadline: Final Freeze
  • Blocks release? Yes
