Emdebian Alternative firmware

This guide shows the procedure to create your rootfs from emdebian distro, There is little Stora specific.

Building the bootstrap image

The image can be build on other architecture like a i386 or AMD64 Debian Desktop.

debootstrap --arch=armel --foreign squeeze grip/ http://www.emdebian.org/grip

Make a a package with the files you have created,

tar cvf emdebian-squeeze.tar grip/

Now copy the file emdebian-squeeze.tar to a webserver or a FAT16 USB stick.

Deploying the bootstrap image

Login the the Store NAS.

Become root:

sudo -s -E

Go to a dir that has more than 200MB free space:

cd /home/

Transfer the tar file to the Store NAS:

wget http://kom.aau.dk/~pmr/emdebian-squeeze.tar #Replace with your own file, if you want.

Extract the file:

tar xvf emdebian-squeeze.tar

chroot to the extracted dir:

/usr/sbin/chroot grip/

Note: If you do not have the command chroot, try installing a package manager.

Create missing dir:

mkdir -p /usr/share/man/man1

Start the bootstrap process:

debootstrap/debootstrap --second-stage -verbose

The bootstrap process will take some time. You will get this message when it is done:

I: Base system installed successfully.

Configuring the installation

Root password

Set the root password:

passwd

Network configuration

Create the file: /etc/network/interfaces

# Loopback
auto lo
iface lo inet loopback

# Ethernet
auto eth0
iface eth0 inet static
        address 192.168.1.93
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 8.8.8.8 8.8.4.4
        hwaddress ether 02:12:34:56:62:40 #Replace with your Stora's MAC address.

Note: You have to modify the file to your network setup. Use the MAC address that is written on a sticker on the back of your Stora.

Modify /etc/resolv.conf

nameserver 8.8.8.8
nameserver 8.8.4.4

Set time zone

Configure the time zone:

dpkg-reconfigure tzdata

Setup fstab

Create the /etc/fstab

#
# /etc/fstab: static file system information.
#
# file system   mount       type    options           dump    pass
#/dev/sda1       /           ext3    defaults          1       1
proc            /proc       proc    defaults          0       0
devpts          /dev/pts    devpts  gid=5,mode=620    0       0
sysfs           /sys        sysfs   defaults          0       0
#/dev/sda3   /home   ext3    defaults,bsdgroups,noatime,nodiratime    0   0
##/dev/md0   /home   xfs    defaults,bsdgroups,noatime,nodiratime    0   0

## other examples, uncomment to activate
#/dev/sda2      swap        swap    defaults          0       0
nodev           /var/log tmpfs
##nodev                 /mnt/tmpfs tmpfs
ubi0:rootfs / ubifs defaults 1 1

And mount /dev/pts:

mount /dev/pts

Setup APT repository

Create the file: /etc/apt/sources.list

deb http://www.emdebian.org/grip/ squeeze main
##deb http://ftp.gva.es/mirror/debian/ squeeze main contrib non-free
deb-src http://www.emdebian.org/grip/ squeeze main

Install SSH

We need to install a ssh server. Here we choose dropbear, because it is lighter than openssh.

aptitude update
aptitude install dropbear

This will give an error because 22 port is in use.

Edit the file /etc/default/dropbear, and change port 22 to port 2222, and then retry:

aptitude install dropbear

Reedit /etc/default/dropbear, and change the port back to 22.

Link the dropbear executable to the standart name of ssh. This will be useful for programs like rsync:

ln -s /usr/bin/dbclient /usr/local/bin/ssh

Other useful packages

aptitude install rsync less sudo host

Install the rootfs

With this filesystem prepared you can follow the MacWire procedure, and install this rootfs onto the stora. :-) To install this rootfs you have to follow this guide [1] using the rootfs filesystem created.

The built rootfilesystem is uploaded to HHU repository.
