Fedora Cloud Edition wants to use a GPT partition table; however, it is not possible
to force the creation of an image with the GPT partition table with our current tooling
because Anaconda requires setting
inst.gpt as a kernel boot parameter
to do it. This Change proposes to add a way to declare this via kickstart so
that the Cloud Edition image builds can create images using the GPT partition table
using the current tooling (which is built on Anaconda).
According to Brian Lane the directive is already accessible from the following command option
clearpart --disklabel gpt
Benefit to Fedora
Users will be able to install systems with a GPT partition table via kickstart without requiring an extensive custom pre-installation script or a custom boot script. Disk images produced using the Anaconda tooling (Oz/ImageFactory, Lorax) can also trivially make images with GPT partition tables. This makes it possible to create hybrid BIOS+UEFI boot images, given the changes to GRUB configuration from Fedora Linux 34.
- Proposal Owners
- Review and discuss with the Anaconda maintainers and determine the next steps for support of the inst.gpt in pykickstart
- Work with Anaconda maintainers to implement in Anaconda
- Release engineering: #10137
- Policies and guidelines: N/A
- Trademark approval: N/A
How to test
Build images using virt-install with kickstarts that have the option set. Verify that the disk partition table is properly configured as GPT. Verify that without the option set, it uses legacy MBR.
- Allows for the use of the standard pykickstart directive for specifying the preference for GPT partition.
