# Need to write several files to help with various things here.
# First, the all-important README :
cat >/home/rocky/README << EOF
== Rocky 8 Raspberry Pi Image (experimental) ==
This is a minimal Rocky 8 install intended for Raspberry Pi 4 devices (architecture is aarch64).
It may work on a Pi 3 , but that has not been tested. We are looking for Rpi 3 owners to test if you'd like to try it.
This image WILL NOT WORK on a Raspberry Pi 1 or 2, we are 64-bit only, and have no support for 32-bit ARM processors. Sorry :-/.
IMAGE NOTES / DIFFERENCES FROM STOCK ROCKY 8:
- Based on Rocky Linux 8.4, 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 / partition, just type the following (as root user):
rootfs-expand

# Next, script to fix the wifi firmware setting:
echo >/home/rocky/fix-wifi-rpi4.sh << EOF
#!/bin/bash
# Simple hacky fix to correct wifi settings on the Rpi4 so it loads properly:
sed -i 's/boardflags3=0x48200100/boardflags3=0x44200100/g' /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt
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; "
