F43 Beta I did 2G /boot/efi and the rest / ext4:
nvme0n1 259:0 0 953.9G 0 disk
├─nvme0n1p1 259:1 0 1.9G 0 part /boot/efi
└─nvme0n1p2 259:2 0 952G 0 part /
It wasn’t complicated, but felt a little tricky to make sure it was set right. The right sidebar tips about required partitions was helpful with /boot/efi!
I’m not sure if it would have worked, but I tried doing no partition table and just adding the partitions; the editor only let me add one partition without size choice. Selecting GPT and then adding the partitions was fine and presented size choice.
