Build Your Own Remix

THIS SHOULD BE LOOKED AT FIRST:http://download.sugarlabs.org/soas/docs/customization-guide

NOTE: this content will be used to enhance above link - 08/03/2010 satellit

CAUTION: DO NOT TRY DOING THIS FROM A SOAS USB STICK or CD. A MINIMUM OF 8GB IS REQUIRED TO BUILD A CUSTOM-REMIX.ISO

8GB is a minimum size requirement.
A 120GB or larger external USB Hard Drive is recommended. Install fedora on it.A Gnome Desktop install seems to work best.
Download Links F13: [1][2]
  • A related project SugarCreationStation is being developed.
A Prebuilt Installer Disk [3]
This will be a Custom Remix CD with livecd-tools and spin-kickstarts installed.
Requires installation to a Hard Disk to allow Building .iso's.
This CD will Provide the tools, including detailed instructions, for creating a custom Soas-remix

The following is Modified/Adapted from: https://fedoraproject.org/wiki/Talk:How_to_create_and_use_a_Live_CD

Introduction

NOTE THAT THESE REMIXES ARE NOT SUPPORTED BY FEDORA
You may find some volunteer support on IRC freenode #sugar however.


This page explains how to make a custom-content Live CD or DVD on Fedora-based systems including derived distributions such as RHEL, CentOS and others.

If you simply want to burn a pre-made ISO to a disc, visit http://fedoraproject.org/en/get-fedora to download a LiveCD or LiveDVD, then see the install guide or burning how-to for further instructions.

Instructions

The basic workflow for creating a remix is:

  1. Create / Modify a kickstart file that specifies the packages you want installed on your remix, along with special settings you want to tweak.
  2. Run that kickstart file through livecd-creator, which will pull in the packages and compose an .iso, which you can then burn to CD.

...that's it! We will walk you through these steps below.

Install the necessary software

To create a live image, the livecd-creator tool is used. Super user privileges are needed. The tool is more or less self-documenting, use the --help option to see options.

The livecd-creator tool is part of the livecd-tools package. If it is not installed on your system, add it with: 

su -c 'yum install livecd-tools spin-kickstarts'

If you are interested in localized live cd files, install also l10n-kickstarts. 

su -c 'yum install l10n-kickstarts'

Note the spin-kickstart files that download are specific for the version of fedora you are using

The version of sugar will also be different for each version of fedora:
f12 0.86.-
f13 0.88.-
f14(rawhide) 0.89.- (0.90.-?)

Set up your environment

Now we'll set up the place you'll be building your remix's image file in. We assume you're running a recent version of Fedora.

We will use the /home/(user*)/Desktop to do our builds
Note: If you use the Kickstart files in the default installed location in /usr/share/spin-kickstarts you will have permission problems editing the files.
  • Set SELinux in permissive mode:
su -c ‘setenforce 0’
  • Copy the fedora-livecd-soas kickstart file you've Downloaded to your Desktop:
(user*)= your user name
mkdir /home/liveuser//home/liveuser/Desktop/spin-kickstarts
cp -r /usr/share/spin-kickstarts/*.ks /home/liveuser/Desktop/spin-kickstarts/


  • Edit one of the .ks files you just copied to your Desktop/spin-kickstarts directory
gedit

Create/Modify the kickstart file

  1. Open the kickstart file you chose from the spin-kickstart folder you copied to your Desktop in the editor of your choice.:
  2. Create the package manifest section and add your favorite packages:

%packages
foo
baz
bar
%end
More Information
  • %packages
Add and or remove programs
Any Program with a minus sign (-) will be removed; any program without a minus will be added
  • %post
Manipulate files that have been installed
%post command are done in cheroot (the commands are only run against the new file system created for the live CD)
  • To change repository: (eg: enable rawhide)
Edit the fedora-live-mini.ks
Put # in front of repos you do not want to use
(remove # )from The repos you want to use
EXAMPLE: repo --name=rawhide --mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=rawhide&arch=$basearch


  • Congrats -- you're done!

Example Terminal Command to Build .iso

You must be connected to a fast Internet connection for this to work

f14(rawhide)build system using fedora-livecd-soas.ks
(This example also works with a f13 Build System)
  • In terminal /home/(user)/Desktop:
su
"#"
livecd-creator \
--config=/home/(user)/Desktop/spin-kickstarts/fedora-livecd-soas.ks \
--fslabel=Soas-v(2-3-4)-mmddyear-Remix --cache=/var/cache/live --verbose
  • KEY
--fslabel=Soas-v(2-3-4)-mmddyear-xxxx-Remix = (The name you specify for the CD remix)
Explanation of format for name: (preliminary layout pending approval by Soas)
v(2-3-4)= the sugar version v(2-3-4)
v2= Fedora 12 sugar 0.86-
v3= Fedora 13 sugar 0.88-
v4= Fedora 14 sugar 0.89-0.90
dd/mm/year= The Creation Date
-xxxx = custom name
Remix is REQUIRED for naming if Soas is used
--config=/home/(user*)/Desktop/spin-kickstarts/ * (path to your Desktop/spin-kickstarts folder and .ks file)

Build the image

  • The build process will take some time, as well as space and bandwidth.
Success is indicated by message:
"Setting supported flag to 0"
your new remix CD.iso is located in your Home Folder.
