Does anybody know why fedora doesn't support vfat/btrfs boot partition?
Is it possible in Fedora 32?

It's possible, but not every tool supports it. I've been running /boot on a btrfs subvolume for a few years now, and I converted it back to a separate ext4 partition just today.
If you create the partition after the installation yourself, copy the files, adapt /etc/fstab and your kernel command line, you should be good. You also need to disable BootloaderSpec (blscfg), since it cannot handle btrfs subvolumes correctly.
I have no idea why Fedora doesn't (want to) support it.

i was quite surprised vfat wasn't supported by anaconda, while xfs does. it's very peculiar.
thanks for sharing.

I think vfat is not supported in such use cases since it doesn’t support Unix file permissions...

at least vfat 32 is supported. i had boot and efi in the same partition. with pxeboot, /boot doesn't even exist.

Fedora 32 actually supports /boot being a btrfs subvolume.
Just swap it in Anaconda at install time and it works.

The UEFI bootloader on your motherboard would have to support it. The UEFI spec currently mandates support for FAT, but a vendor could add support for other fileystems if they wanted to but AFAIK most don't.
No, I'm not talking about esp(/boot/efi). It's already formatted as vfat. I'm taking about /boot which is at the moment xfs in my case. anaconda doesn't seem to allow it.
