Here is a working SD card image for installing Arch Linux on an OrangePi Zero. It basically follows [this excellent build guide][build-guide] but can save you a lot of time if you just want to get an image up an running, especially with getting the ethernet support to work.
Once the system is working, use `fdisk /dev/mmcblk0` ([fdisk][fdisk]) as root to resize the partition. Press `d` to delete the current partition, then press `n` to create a new partition, and press `Enter` 4 times to accept the defaults. fdisk will give you defaults that work and make the partition as big as possible. Then answer `N` when fdisk asks about removing the existing ext4 signature.
