Description Neal Gompa 2021-07-04 14:59:58 UTC 
Description of problem:
When installing as hybrid BIOS+UEFI on GPT, Anaconda sets the pmbr_boot flag by default on the volume, which makes it unbootable with OVMF-based UEFI environments (which is nearly all of them).

To solve this, it'd be great to have a flag for "clearpart" that makes it possible to tell Anaconda to tell Blivet to not set the pmbr_boot flag on the disk.

As a suggestion, something like "--no-gpt-pmbr-boot-flag" for clearpart would do the trick.

Version-Release number of selected component (if applicable):
35.18-1.fc35
