Stefan,
Your comments about the timeline are well placed. Thanks. That does
change things a little. I've just managed to get LISAsoft management
signoff to have you work on this project till the end of the week.
So I propose:
1. Stefan installs a number of projects that he is already familiar with
from the Arramagong DVD onto Richardo's latest GISVM.
2. Write .sh scripts to do the installation, then execute them. (Note,
the scripts should be written under the assumption that root will be
executing them. So no need to use "sudo" in the script).
By writing the scripts, we should be able to provide examples for others
to follow.
3. Richardo, if he has time, should write scripts for the projects that
he would like to install, which Stefan can then apply to the image being
built at LISAsoft.
4. By this Friday 28 Aug, we will have a draft image, which we upload
for the community to review.
4.5 By Friday, we will also have the wiki pages up to date, with one
page explaining how to get your project into the GISVM. I can commit to
making that happen.
5. On Friday, I'll send out a press release inviting projects to write
install scripts for other projects, and noting the timeline, along with
a message "Get your scripts written onto the liveDVD the following week
if you want your project distributed at FOSS4G".
6. I expect we will get 1/2 the projects to contribute, we can also add
a few more projects ourselves in that week.
Somewhere during this, lets try and organise a synchronisation box, but
I don't think that is the most important task, and if it doesn't get
done until after foss4g, that is ok.

>>> Assunto: [Live-demo] More ideas on collaborative development
>>>
>>> I've been thinking hard about recent comments from Hamish, Massimo, Richardo and Stefan in relation to collaborative development of GISVM and LiveDVD. I've also been looking over the wiki pages and svn scripts and the GISVM to see what has been done already. After sleeping on this for a few nights, I wonder what people think about the following ideas:
>>>
>>> 1. Write install scripts for each application, and put these scripts into subversion:
>>>
>>> I suggest we create bash install scripts for each application we want on the LiveDVD. These scripts will contain all the steps necessary to install a project. Ie, we would have one script for geoserver, one for mapserver, one for qgis, etc.
>>>
>>> I notice that Massimo is part way here, having written the installation steps into the wiki at:
>>> http://wiki.osgeo.org/wiki/GFOSS.it_Live_DVD_Install
>>>
>>> Stefan has created a similar wiki at:
>>> http://wiki.osgeo.org/wiki/LISAsoft-LiveCD_process
>>> Stefan has also been collecting these steps into scripts stored in subversion:
>>> https://svn.osgeo.org/osgeo/livedvd/scripts/trunk/LiveDVDFromScratch/
>>>
>>> The key points here is:
>>> * Community engagement: It would be straight forward for projects to write their own installation scripts. They can write them, then copy into svn, then let one of the VM team members apply to the latest virtual machine.
>>> * The scripts will be kept under version control. (Following on from a comment from Hamish about the value of svn)
>>> * If a .deb file exists for a project, all the better. The install script will just be one line long.
>>> * These scripts could be integrated into a greater build script as we progress.
>>> * I expect these bash scripts would eventually become the basis of a .deb file?
>>>
>>> 2. Xubuntu:
>>> I suggest that we use Xubuntu as a basis for the GISVM instead of Ubuntu, as it is specifically designed to run on a low powered environment, but still runs all the Ubuntu packages.
>>>
>>> 3. Wiki pages:
>>> There are a few too many LiveDVD wiki pages, which makes it hard for a newbie to find out what is current, and what is not.
>>> http://wiki.osgeo.org/wiki/Category:Live-demo
>>> I suggest that we consolidate down to a few pages, removing content from some pages and just providing a pointer to more recent pages.
>>>
>>> 4. Central VM, which we rsync from:
>>> As mentioned earlier, I think that we should set up a central virtual machine, probably on OSGeo hardware, which we can all rsync from in order to collaboratively update the same virtual machine.
>>>
>>> I'm interested to hear feedback on this, and I'd like to help out on some of these tasks, if they are considered worth following.
