Creating a Fedora AArch64 Image for the RPi 4

Prerequisites:
- A working Fedora installation
Install arm-image-installer:
```
sudo dnf install arm-image-installer
```

Define the base image and download components:

export RELEASE=33
export IMAGE=Fedora-Minimal-33-1.3

wget https://download.fedoraproject.org/pub/fedora-secondary/releases/$RELEASE/Spins/aarch64/images/$IMAGE.aarch64.raw.xz
wget https://raw.githubusercontent.com/KizzyCode/well_known_id_rsa/master/well_known_id_rsa.pub

⚠️ Important: ⚠️ We deploy the well_known_id_rsa public key for root; so be aware that you remove this key from /root/.ssh/authorized_keys during deployment/setup

Create and attach an 8 GiB working image:

dd if=/dev/zero bs=1M count=8192 | speed > $IMAGE.rpi4.img
sudo losetup -f $IMAGE.rpi4.img && losetup -l

Create the image (where loop0 must be replaced with the real loop device from the step above):

export LOOP=/dev/loop0
sudo arm-image-installer --target=rpi4 \
    --image=$IMAGE.aarch64.raw.xz --media=$LOOP \
    --addkey=well_known_id_rsa.pub \
    --relabel --resizefs
sudo losetup -d $LOOP

Wait up to 10 minutes for the initial setup after powering the RasPi and login as root via SSH using the well_known_id_rsa key

[Optional] Create an xz-compressed template from the image:

speed < $IMAGE.rpi4.img | xz -ce -T 8 > $IMAGE.rpi4.img.xz
