How to install voidlinux in an orangepi zero.

* insert sd card in adapter/reader/whatever, mine appears as /dev/sdb
* cat OrangePi_zero_ubuntu_xenial_server_linux5.3.5_v1.0.img > /dev/sdb
* mount /dev/sdb2 (in my case, in /media/rootfs)
* cd /media/rootfs 
* tar cpvfz /path/to/yourchoiceofname.tar.gz etc/fstab lib/modules/ lib/firmware/
* rm everything in /media/rootfs
* cd /path/to/void..rootfs 
* tar -C /media/rootfs/ -xvf void-armv7l-musl-ROOTFS-20191109.tar.xz
* tar -C /media/rootfs/ -xvf yourchoiceofname.tar.gz
* cd /media/rootfs/etc/runit/runsvid/default 
* ln -s /etc/sv/agetty-ttyS0 agetty-ttyS0
* cd && umount /media/rootfs
* connect usb-ttl adapter to opizero, insert sd-card
* screen /dev/ttyUSB0 115200
* connect opizero to power source and see how it boots and present you the login screen.
