As Andreas mentioned, it's not cross distro issue since all distros have different tools to create live media.
Next week I'm planing to have the first medical project meeting. I'll inform you about.
Following what mentioned: http://lists.opensuse.org/opensuse-medical/2011-11/msg00007.html
I was searching a way how to create a live cd fully functional.
I think that you will not be able to create a LiveCD with fully functional MySQL, PostGreSQL servers. If you succeed with an installation of these server, data will be lost at each restart.
Assuming that your wishes are:
- distributing an easy system for app testing
- install and preconfigure medical&related apps
- make this fully installable (system and config) to any computer
You're right. This media will be easy to test pre-configured applications and those applications will be fully installed after installation. Doctors (people who don't care about computers) want something that works (proprietary or not). If the live media won't work, then they won't test it before install it.
I was testing a lot of things, even with other distros to understand how things work (unfortunately it's not my job to do that). Well, I managed to create an appliance on mint (it works after installation) and I also managed on PCLinuxOS (http://sourceforge.net/projects/pclosmedical/).
As Sebastian mentioned, there's an appliance of GNUMed on SUSE Studio that works. Matt said about the use the "modified files" feature on SUSE Studio. It's something I'll start now and I'll be back soon.
Thanks for your help Stathis
