Description Paul Whalen 2018-02-13 21:19:19 UTC 
Description of problem:
On a default install on aarch64 efi systems, the disk uses MBR partitioning rather than the expected GPT.

Comment 6 Peter Robinson 2018-02-14 11:21:09 UTC 
This logic is handled in blivet. It's changed a lot since I last looked at it but I suspect some logic was lost in upstream commit ebd43b67aaeae8bd969c5ef9ba7280a03f8f4935
Comment 7 Fedora End Of Life 2018-02-20 15:34:48 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
