Installation

# Enlarge the tmpfs root partition
mount -o remount,size=1g /

# Install some stuff we need to install CRUX
apt update
apt install -y xz-utils

# Partition the disk; SWAP / BOOT / ROOT partitions
sgdisk -Z /dev/sda
sgdisk -n 1:0:+2G -t 1:8200 -n 2:0:+32M -t 2:8300 -n 3:0:0 -t 3:8300 /dev/sda

# Format the partitions; note that BOOT partition needs to have 64 bit and metadata checksum features turned off
mkswap /dev/sda1
mkfs.ext4 -F -O ^64bit /dev/sda2
mkfs.ext4 -F /dev/sda3

# Mount the partitions
swapon /dev/sda1
mount /dev/sda3 /mnt
mkdir -p /mnt/boot
mount /dev/sda2 /mnt/boot

# Unpack the rootfs tarball
wget http://resources.crux-arm.nu/releases/3.4/crux-arm-rootfs-3.4.tar.xz
tar -x -f crux-arm-rootfs-3.4.tar.xz -C /mnt
rm crux-arm-rootfs-3.4.tar.xz
