GNUmed Live CD/DVD

GNUmed Live CD/DVD / USB (image) is available from the Sourceforge and SUSE studio

Put GNUmed Live on a CD/DVD

It is based on openSUSE. It is a version of Linux which will run right off the DVD or an USB drive, with no installation necessary. It does not change anything on your Computer. From the downloaded image (iso) file you can produce a DVD or USB GNUmed demo.

Prepare and run the GNUmed Live DVD

Given you have a PC which can start from DVD, all you have to do is download the DVD. Then use a program like k3b or xcdroast for Linux, Mac or a Windows program to burn the so called ISO image - the file you downloaded. Whatever burn program you use, don't burn the downloaded file as a file but rather find the option where it lets you burn bootable CD images. Any decent CD burning app should have this option (beware, the free Nero doesn't).

Then put the DVD in the drive and let your PC start from it. It will boot into a graphical environment (KDE). It will present you with a desktop icon which lets you start GNUmed. You can use this CD to connect to the public database over the internet or you can use a database provided right there on the DVD. Yes, that is right. A local GNUmed server can be started from this very DVD as well.

So all you need is this DVD, premade to provide an English, German, Spanish or French user interface.

Tip: Run Live-DVD image file from a virtual drive without burning a real DVD

Vmware, Virtualbox and Qemu are software products that let you run the Live-CD (image) from a virtual CD-ROM drive. See their documentation on how to set up a virtual machine with a virtual CD-drive.

As an example a short video showing how to use the Live-CD file (without burning the CD) inside Virtualbox is provided for your convenience.

Put GNUmed Live on an USB drive

There is a nice tool called UNetbootin available for download which will let you install the downloaded CD image (iso file) into a USB drive. Given you have a computer which can boot from USB drives (most recent PC can do this) simply select USB option at the computers startup and it will start GNUmed from the USB drive without altering your PC's harddrive.

Don't say we don't make it easy to test and use GNUmed.


Build your own Live-CD

Prepare from Template

Download http://www.gnumed.de/downloads/live-cd/config.tgz. Unpack it to a directory like /root/debian-live. Change into that directory and and run 'lh_build'

Prepare from scratch

For the time being we want to build a live CD for Debian Lenny which is also called testing until Debian 5.0 is released. You can build the CD if you use Debian etch ( current stable version ) or Debian Lenny (current testing version). If you don't habe Debian installed on you Computer you can still help by running the whole process in a virtual machine. I have an image of Debian Lenny running in Vmware Vmplayer. The player is free as in beer and does the job.

General information is on the Debian-Live project page. Generating a Debian Live CD is very simple. You need to have live-helper (package available in Debian sid and lenny), and Debootstrap (or cdebootstrap) from Lenny or newer.

To mix Debian Etch (stable) , Lenny (testing) and Sid (testing) we need to set up apt-pinning in /etc/apt/preferences

Package: *
Pin: release a=stable
Pin-Priority: 700

Package: *
Pin: release a=testing
Pin-Priority: 650

Package: *
Pin: release a=unstable
Pin-Priority: 600

Now as root you simply issue in a cmd shell : 'apt-get install -t testing live-helper' and 'apt-get install cdebootstrap'. You are now set to build the CD. I recommend you set up a directory called debian-live in the root directory. The Live-CD will be created in this directory.

In this directory issue the following commands:

lh_config -p xfce -d lenny --packages gnumed-client gnumed-client-de mc postgresql sudo

lh_config --debian-installer=enabled

Start the Build

You are now set. Run 'lh_clean --purge' followed by 'lh_build' and you are on your way. The result is a file called 'binary.iso'.

Customizing the CD

Take a look at the files in the config directory and add files or change files there. Then run lh_clean and lh_build again.
