This is a very important issue!
Many have asked for a development version of GISVM.
(never done it because it was to advanced for me. heheh)

My proposal is that we make a different version of Live Demo / GISVM for that purpose.
Name it as you which: Development, Advanced or Unstable

Best,
RP

Hi Cameron,

Little update on what i'm doing :

Actually i'm hard-working on a sidux live.iso produced by a virtualbox VM,
doing regular update && dist-upgrade.
The sidux distro use debian-sid, sidux (including debian-gis repository)
It use the latest kernel and updated packages (i added the non-free repository too)

For some reason i prefer to build some sw from svn source code : Gdal, Grass, OpenScenaGraph, Ossim, Qgis, Mapserver, Mapnik, Libtiff, Libgeotiff, GpsTK).
and other sw from tarball (pgadmin3 and some others)

"""  about svn sw against stable version ... :
i prefer to have development (svn) version, in this way i can do an intense testing process using it
in my short experience i find more bugs in the stable version rather than the svn version (this can  be not true for you .. i agree, but this is my experience)
.
If we have time to give a look, every day, in the svn boot logs ...  for each application we are intersted for, in this way we know if there is a commit that represent an  update or a bug fix changes.
knowing the svn progress we can test the new enanchments and debug it if/where it is possible.
in this way the sw development go ahead more fast (if we provide logs, ticket or feedback .. using m-list and irc) and if (unlucky) a bug come up and no solution/fix is ready we can even do svn -r "release-without the critical bug" to checkout a good revision tagged as "svn-stable"  """

(odd : using a source build for gdal i need to build from source all the sw that depends on it, but it ensures me to have a working gdal version without generate conflict bettween variouse tools that uses gdal (see gdal-grass and ossim-gdal plug-in).

What i'm including in the .iso :

- sw we have in the last osgeo dvd (need to add java apps yet, using the free jdm and not the sun jvm)
(i agree that we need a full detailed list about the software We want install on the live disc)
- ossim+3d stuff
- updated grass6.5 and qgis1.2  svn version (plus all the qgis-python plug-in and some grass addons)
- other scientific sw like octave (+qt interface) and variouse plotting tools
- R with spatial packages already installed
- gmt + mbsystem
- some FEM (finite elements) sw
- database managment sw (pgadmin3, phppgadmin)
- openoffice 3 complete suite, gimp, inkskape
- latex tools
- development kit + dev packages headers (compilers and tools like gcc, jam, ant, scons, etc... and the needed -dev dependencies to build sw from source)
- sidux help file in all avaiable language.

i need to add  yet the java sw (geoserver, geonetwork, udig+javagrass, josm ... others?)
here i need help and i'll give a depth look at the future scripts to configure them.

i'm planning to add also OMAR (ossim mapping archive),  OTB (Orfeo Toolbox) and tilecache + GeoDjango

I'm installing sw from source instead of use what the debian-repository already has beacouse :

- installing sw from svn or source tar.gz  give us a distro that is really up-to-date, and it is aslo "upgradable"
every time the user needs an upgrade, beacouse it already has all the needed dependencies (-dev
packages) and i'll provide scripts to update configure and make the sw installed from source.

- there are some packages (sdl, libtiff, pyqwt, pgadmin3, ... others) with some problems and bugs
so installing from source i can avoid to have bugus sw installed

I choose sidux instead of debian stable or ubuntu beacouse :

-  it has more updated packages and it is a stabilized sidux distro

-  using sidux it already install in the .iso some virtualizzation tools that give us :
  in a VirtualBox Machine, just select the sidux.iso in virtualbox as bootable device and the VM will have
  expanding desktop and 3d environment ready to use in the VM   (ose version)

(the downloaded iso is about 450 mb, it is really thin)
starting from it id done a apt-get update apt-get dist-upgrade (adding the non-free repository too)
i added script to rebuild the SW installed from source. the final .iso size is near 2.3 gb

For sure, i can test the scripts without problems and adapt it to works on sidux.
I need help for the java apps beacouse i never used it too much i'm able to install Geonetwork and Geoserver (based on tomcat)...  but i never configured it to works on data (step needed to have a working geoserver/geonetwork demo).

For openlayer+Tilecache+Mapnik+ Osm(including tools like osm2pgsql and mapnik rendering)) i can ask on the relative #irc channels to find help to configure a good example-project.

My idea is to provide to the user not only sw, but an easy way to try it out too.
Provide too much data for test all the sw installed is not a good thing so i decided to use
as demo-examples data the same demostration files for variouse sw (where applicable).

(thanks to the gdal-grass-plug-in and the ossim-gdal-plug-in we can use the same dataset for variouse project, without data duplications and without needs to download data after the iso is running)

So simply, i'm using for  Mapserver (i use kamap as frontend for ms), Qgis, Grass, Ossim the same demostration files  based on a Grass location (unzipped spearfish is only 60mb).

But i should like  to have also :

- a global-dataset for all the .iso users  (world coastlines and countries boundaries, lake, stream) and a world.jpg lightweight raster image.
- a localized dataset + localized tutorial (downloadable from osgeo)

Right now i'm installing some sw on the VM and debugging it to see if all works as aspected
i'm avaiable to provide any kind of test and feedback.
if yoy know a good place where to upload a testing.iso image i can provide you a test-alfa release at the end of this week.

apologize me for the not perfect english, i hope i gived you a good and not confuse explanation
about what i'm doing.

let me know what can i do to help us to work on the foss4g live dvd project.

p.s..:
unlucky we are on different distro (this don't help) but i will not use ubuntu beacouse it gived me some problems in the past, tring to use ossim+3d stuff beacouse it doesn't have an up-to-date kernel that can runs well on my laptop-hardware (this the reason i switched to sidux, i was an ex happy-ubuntu user)

Ciao,

Massimo.
