Comment 3 for bug 1857789

I believe the partitions are being created in the wrong order. By manually partitioning, I have been able to get a bootable system with the following created in lsblk:

sda 8:0 0 3.7T 0 disk
├─sda1 8:1 0 1M 0 part
└─sda2 8:2 0 3.7T 0 part /

When I was in a chroot environment on the non-booting default partition scheme, the 1M partition was at the end of the drive as sda2. I believe the installer is partitioning the drive incorrectly when accepting the defaults.
