# Kickstart to build Rocky 8 image for Raspberry Pi 4 hardware (aarch64)
# (many parts liberally grabbed from pgreco: )
# Here is how to build this kickstart Raspberry Pi image, inside a clean mock chroot environment with livemedia-creator:
# (it is very similar to how the other kickstarts are built, but aarch64 must be used, and the livemedia appliance option)
# Set up mock env, and get a shell inside the chroot:
# mock -r rocky-8-aarch64 --init
# mock -r rocky-8-aarch64 --install lorax-lmc-novirt vim pykickstart git
# sudo setenforce 0
# mock -r rocky-8-aarch64 --shell --isolation=simple --enable-network
# Inside the shell:
# git clone
# git checkout r8
# cd kickstarts/altarch
# Finally, run the image creation:
# livemedia-creator --ks rockyrpi.ks --image-only --image-name RockyRpi --make-disk --resultdir /rockyrpi_result --no-virt
# Disk setup

== Rocky 8 Raspberry Pi Image ==
This is a Rocky 8 install intended for Raspberry Pi 3b and 4 devices (architecture is aarch64).
This image WILL NOT WORK on a Raspberry Pi 1 or 2 (1.1 or earlier), we are 64-bit only, and have no support for 32-bit ARM processors. Sorry :-/.
The newer Pi Zero devices should be supported, as well as the Raspberry Pi 2 v. 1.2 boards, which are 64-bit
- Based on Rocky Linux 8, points to production Rocky 8 aarch64 repositories
- Has an additional repository that contains kernel packages for Raspberry Pi
- Includes script that fixes the wifi. Simple edit of a txt firmware settings file. Will need to be run whenever linux-firmware gets upgraded
- Includes @minimal-install , plus a few quality of life packages like vim, bash-completion, etc.
- Initial User "rocky" (default password: "rockylinux"). Root password disabled, rocky user is a sudoer
- Partitions are 300 MB /boot , 512 MB swap, 2800 MB rootfs. Requires a 4 GB or larger storage device to serve as your disk
If you want to automatically resize your root (/ ) partition, just type the following (as root user):
sudo rootfs-expand
It should fill your main rootfs partition to the end of the disk.

# Next, script to fix the wifi firmware setting:
cat >/home/rocky/ << 'EOF'
# Simple hacky fix to correct wifi settings on the Rpi4 so it loads properly:

echo "Patched /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt . You can reboot and wifi should work, or do: rmmod brcmfmac; modprobe brcmfmac; "
