How to Install Linaro nano 14.03 (minimal headless system)

Copied here from Shodruk's forum post.

Requirements

Ubuntu PC, SD Card, SD Card adapter, Parallella

On the PC's terminal:

Download the files

wget -O rel.14.02.06.tgz https://github.com/parallella/parallella-bin/blob/master/rel.14.02.06.tgz?raw=true

wget http://releases.linaro.org/14.03/ubuntu/saucy-images/nano/linaro-saucy-nano-20140323-649.tar.gz
md5sum rel.14.02.06.tgz

Determine the device name of the SD Card

sudo parted -l

In case of a 2GB SD Card:

Model: SD/MM Reader
Disk /dev/sdX: 2042MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
1 1049kB 49.3MB 48.2MB primary fat16
2 49.3MB 2042MB 1992MB primary ext4

"/dev/sdX" is the device name of the SD Card
(e.g. sdb, sdc, sdd, sde, mmcblk0, mmcblk1, ... and, Beware! Don't partition HDD!!!)

Partition the SD Card

Unmount the SD Card if it was automounted, then,

sudo parted -a optimal /dev/sdX

(parted) print

If there are two partitions on the SD Card,

Number Start End Size Type File system Flags
1 1049kB 99.6MB 98.6MB primary fat16 lba
2 99.6MB 2042MB 1942MB primary

Delete all existing partition

(parted) rm 2
(parted) rm 1

Make new partitions

(parted) mkpart p fat32 2048s 100m
(parted) mkpart p ext2 100m -1m
(parted) q

Check the partition

sudo fdisk -l /dev/sdX
Device Boot Start End Blocks Id System
/dev/sdX1 2048 194559 96256 c W95 FAT32 (LBA)
/dev/sdX2 194560 3987455 1896448 83 Linux

Format the partition

sudo mkfs.vfat -n BOOT /dev/sdX1
sudo mkfs.ext4 -L rootfs /dev/sdX2

Extract rootfs

sudo mkdir /tmp/mnt1 /tmp/mnt2
sudo mount /dev/sdX2 /tmp/mnt1
sudo tar --strip-components=1 -C /tmp/mnt1 -xzpf linaro-saucy-nano-20140323-649.tar.gz
sudo sync
sudo umount /tmp/mnt1

Extract BOOT partition

sudo mount -o umask=000 -t vfat /dev/sdX1 /tmp/mnt2
sudo tar -C /tmp/mnt2 -xzf rel.14.02.06.tgz

(The warning "Cannot change ownership..." can be ignored.)

sudo sync
sudo umount /tmp/mnt2

Edit some configuration files

Preventing to install unnecessary packages

sudo mount /dev/sdX2 /tmp/mnt1
sudo nano /tmp/mnt1/etc/apt/apt.conf.d/00InstallRecommends

(Edit and save.)

APT::Install-Recommends "false";

Network configuration

If your router's IP address is 192.168.0.1 and the Parallella's IP address is 192.168.0.2,

sudo nano /tmp/mnt1/etc/network/interfaces

(Edit and save.)

source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

auto eth0

# static network settings
iface eth0 inet static
   address 192.168.0.2
   netmask 255.255.255.0
   gateway 192.168.0.1
   up sleep 3; mii-tool -F 1000baseT-FD

# If you prefer DHCP, comment out the above 5 lines, uncomment the below.
#iface eth0 inet dhcp
sudo nano /tmp/mnt1/etc/resolv.conf
nameserver 192.168.0.1
sudo sync
sudo umount /tmp/mnt1

Insert the SD Card to the Parallella,
power-on,
Wait 30 seconds,
You'll see a root terminal.
If it doesn't boot, press the reset button and try again.

Install openssh-server

On the Parallella:

apt-get update
apt-get install openssh-server
sync

Now you can login the Parallella from your PC.
On the PC,

ssh linaro@192.168.0.2
password: linaro

Create device nodes

sudo mknod -m 600 /dev/ttyPS0 c 251 0
sudo chown root:tty /dev/ttyPS0

Let's see how lightweight it is
