Fedora + Raspberry Pi 4
As stated in the wiki, #Fedora is still not officially supported on the #Raspberry Pi 4.
However you can install it, and it somehow works.
sudo arm-image-installer --image=Fedora-Minimal-33-1.3.aarch64.raw.xz --media=/dev/mmcblk0 --resizefs --target=rpi4
HDMI works, but I didn't test any DE, I used only the terminal.
WiFi seems to work pretty well.
All the 8GB of RAM are visible.
All the four CPU cores are visible.

Serial console works.
Overall performance is pretty good. Compared to a #RPi 3, the RPi 4 is far more fast.
