Difference between revisions of "Building a Custom Raspbian Image"

Revision as of 10:24, 12 October 2012

This page lists the differences between the default Raspbian wheezy image and the one from the Open Lighting Project. If you create your own install from scratch you probably want to do most of these changes as well. The goal of this image is to produce an image as small as possible for end user use. To this aim, development packages, compilers and non-essential packages are removed.

• Password for the pi account changed to 'openlighting'
• Rootfs expanded to 4GB using `sudo raspi-config`
• Simon's key installed into /home/pi/.ssh/authorized_keys
• Timezone set to US/Pacific
• Added the Open Lighting Debian Repo to /etc/apt/sources.lists : deb http://apt.openlighting.org/raspbian wheezy main
• Root ssh access has been disabled in /etc/ssh/sshd_config

• Packages installed:

screen vim ola ola-rdm-tests  deborphan debfoster localepurge

• Packages removed:

dbus-x11 desktop-base desktop-file-utils dillo gdb gdbserver gconf-service gconf2 gconf2-common gnome-icon-theme gnome-themes-standard gpicview

• Remove orphaned packages:

 deborphan | xargs apt-get -y  remove --purge 

• Purge removed packages (if you didn't use --purge above)

dpkg -l |  awk ' /^rc/ {print $2}' | xargs apt-get -y remove --purge

• Finally run

apt-get update && apt-get upgrade
apt-get autoremove 
apt-get clean

Git Image

The following additional changes are done for the git image. The ola debian package normally does this, but since we're installing from source we need to do it ourselves.

• Many unused packages have been removed (samba, X, mysql, nfs etc.)
• /etc/rc.local has been modified to regenerate the ssh keys on the first boot

• OLA dependancies have been installed (microhttpd, libusb, etc.)
• The OLA git repo has been cloned into /home/ola/ola
• The ola account was added and added to the dialout & plugdev groups
• /etc/udev/rules.d/10-local.rules was updated according to OLA_Device_Specific_Configuration
