Create ArchLinux ARM bootstrap image for RPi

rpi-aarch64.sh

#!/bin/bash

mkdir aarch64
mount --bind aarch64 aarch64

pacstrap -c -K -M aarch64 base archlinuxarm-keyring dhcpcd \
        net-tools openssh vi which \
        firmware-raspberrypi linux-rpi \
        iw ldns less openresolv \
        wireless-regdb wireless_tools wpa_supplicant 

arch-chroot aarch64 sh -c "systemctl enable systemd-networkd"
arch-chroot aarch64 sh -c "systemctl enable systemd-resolved"
arch-chroot aarch64 sh -c "systemctl enable systemd-timesyncd"
arch-chroot aarch64 sh -c "systemctl enable sshd"
arch-chroot aarch64 sh -c "useradd alarm -G wheel -m"
arch-chroot aarch64 sh -c "echo "root" | passwd -s root"
arch-chroot aarch64 sh -c "echo "alarm" | passwd -s alarm"
arch-chroot aarch64 sh -c "echo "alarm" > /etc/hostname"

rm -rf aarch64/etc/pacman.d/gnupg
rm -rf aarch64/etc/machine-id

umount aarch64

Works also with docker images.
e.g.:

# Don't forget to install emulation:
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
# Create archarm container, run script inside of it:
docker run --privileged --platform=linux/arm64/v8 --rm -it menci/archlinuxarm 

Awesome gist! I was able to generate the image. Im now trying to user default archlinux docker image with qemu-XXXX-static and archlinuxarm pacman.conf...

On the other side... do you know why I do get wifi with dhcp on pi4 but not on pi3? how can it be fixed? Im using wpa_supplicant

it was some bug in the broadcom driver in upstream kernel or broadcom firmware, not sure. on some of my devices I was forced to use workaround:

$ cat /etc/modprobe.d/brcmfmac.conf
options brcmfmac roamoff=1 feature_disable=0x82000

Wow! Magic! Thank you!!! several days wasted to make wifi work on the pi02w and pi3!
