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 It should fill your main rootfs partition to the end of the disk.
