= Installation =

Here i describe my own detailed installation routine, so i remember what steps i need to take for a fully working test system.

Disable extensive versioning
Remove CONFIG_LOCALVERSION_AUTO or: General Setup ---> [ ] Automatically append version information to the version string

Rootfs
Select an Ubuntu Core Rootfs.

Serial access
Add etc/init/ttyS0.conf so that upstart starts a serial console on ttyS0:


 * 1) ttyS0 - getty
 * 2) This service maintains a getty on ttyS0 from the point the system is
 * 3) started until it is shut down again.
 * 1) started until it is shut down again.

start on stopped rc or RUNLEVEL=[12345] stop on runlevel [!12345]

respawn exec /sbin/getty -L 115200 ttyS0 vt102

To be able to log in as root later on, edit etc/shadow and change from: root:*:15629:0:99999:7::: to root::15629:0:99999:7:::

This will get fixed once you run passwd.

Stop boot from waiting for ages for auto interfaces
Edit /etc/init/failsafe.conf, and reduce the script block to:

script exec initctl emit --no-wait failsafe-boot end script

This gets you a terminal or desktop much, much faster in case usb is not attached.

Disable NetworkManager
This humongous heap of redhat shit always gets in the way, so kill it with fire...

echo "manual" > etc/init/network-manager.override

Add Ethernet
Edit etc/modules and add: sunxi_gmac

Edit etc/network/interfaces and add: auto eth0 iface eth0 inet dhcp

(OR) Add usb ethernet
Edit etc/modules and add: g_ether

Edit etc/modprobe.d/g_ether.conf options g_ether host_addr=22:AA:F2:BB:12:DB

Edit etc/network/interfaces and add: auto usb0 iface usb0 inet static address 192.168.4.2 netmask 255.255.255.0 gateway 192.168.4.1

The latter line is to make sure that routing is setup.

Setup name resolution
echo "nameserver 192.168.1.1" > etc/resolv.conf

USB Host networking setup
So that our device can access the web through usb networking, we need to enable routing/nat on the host computer.

Enable forwarding: echo 1 > /proc/sys/net/ipv4/ip_forward

Set up iptables, with usb1 the usb connection with the device, and eth1 the wlan adapter:

iptables -A FORWARD -i eth1 -o usb1 -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i usb1 -o eth1 -j ACCEPT

iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

Initial setup
Now you should be able to boot this image and log into it through serial.

root password
Set a root password: passwd

Hostname
Run: echo "newname" > /etc/hostname

packages
First, add universe packages in /etc/apt/sources.list

Then run: apt-get update apt-get upgrade

Then, install some basics:

apt-get install ubuntu-minimal nano wireless-tools wpasupplicant usbutils

Depending on Ubuntu version you either need to run:

apt-get install openssh-utils or apt-get install openssh-server openssh-client

locale
locale-gen en_US.UTF-8

user
adduser user adduser user video

Remove usb ether gateway
Remove: gateway 192.168.4.1 from etc/network/interfaces.

Add wifi
Edit /etc/modules and add: 8192cu

Edit /etc/network/interfaces and add: auto wlan0 iface wlan0 inet dhcp wpa-ssid ssid wpa-psk key

Packages
First, make sure that the universe package repository is enabled in /etc/apt/sources.list.

Then, run: apt-get update again.

apt-get install xfce4 xubuntu-default-settings lightdm

Default login
Add the following to /etc/lightdm/lightdm.conf.d/10-xubuntu.conf, under the SeatDefaults section:

autologin-user=user
