When I install Bananian on a Banana Pi this is what I do:

vim

Install vim as default editor

apt-get -y install vim

Crontab editor

Change crontab editor to be vim

update-alternatives --config editor

Change Shell from zsh to bash

chsh -s /bin/bash

Install the latest kernel

apt-get -y install linux-image-4.4-bananian

swapoff /swapfile1

vi /etc/fstab

prefix the line with a hash '#'

/swapfile1 swap swap defaults 0 0

delete swapfile

rm -f /swapfile1
