Summary	0018187: GPT disk check on BIOS-based host doesn't take into account if disk is boot
Description	In 8.2 with anaconda-29.19.2.17-1.el8 the following works: clearpart --drives=sdb,sda --all zerombr # / partition part / --fstype=ext4 --fsoptions='relatime' --size=1 --grow --ondisk=sdb # /opt/var partition part /opt/var --fstype=ext4 --fsoptions='relatime' --size=1 --grow --ondisk=sda In 8.3 with 33.16.3.26-2.el8.centos it fails with: Found sanity error: Your BIOS-based system needs a special partition to boot from a GPT disk label. To continue, please create a 1MiB 'biosboot' type partition. But it isn't a boot disk. In the current version, as long as a GPT disk comes after a valid MBR-based / partition, everything is fine, but on some hardware, the MBR disk is sdb, not sda.
Steps To Reproduce	Kickstart a host where a > 2TB (GPT) disk disk is tested before a valid MBR disk (i.e where the /dev/sdX name of the GPT disk comes alphabetically before the MBR disk).
Additional Information	On hosts where the MBR disk /dev/sda, everything is fine with later GPT disks.
Tags	No tags attached.
