Ubuntu Remaster is a set of automated scripts for taking a stock ISO distribution image from Canonical and recreating it with changes and additional content. It is broken up into layered branches to allow you to make your own optionally encrypted ISO images. Customizers can branch off various 'layers' to add their custom content to an existing image. This branch extends the master branch to create the GNU Radio Live SDR Environment image. Using the Ubuntu Remaster build scripts To create a remastered Ubuntu ISO file, with no further customization beyond what is done in these scripts, simply do the following: $ git clone -b <desired branch> git://github.com/jmcorgan/ubuntu-remaster.git $ cd ubuntu-remaster $ make deps $ make config $ make This will require 'sudo' access. Everything is completely automated, except for passphrase entry when making an encrypted image (see below), and possible password prompts for 'sudo' operation.
