I really wounder about the gisvm svn folder that is still on the DVD and not really required for the projects I guess. IMHO I would remove these 180 MB gisvm directory after successfully installation. Was it an initial thought to let this folder still on it to "develop" gisvm and try install_scripts after roll out? If so it should be still on it. But I guess the user who wants to try any of this project do not really wants to know how to install (in a specific way) the software components itself.<div>

</div>Yes I use a rule of thumb 50%. So 200 MB in the OS tends to be 100MB in<br>
the ISO. This has been fairly true for all of our builds in the past<br>
though currently we're shrinking 9.8 to 3.8 which is more than 50%<br>
savings. The nice part is if you don't go down to the individual file<br>
level it seems to average out compressible vs non.<br>
<br>
Inkscape is being used in Cartography these days (I should know I did a<br>
class with it last year and my friend is giving a talk about it at<br>
FOSS4G). I believe we already removed gimp, and OOo was never on Xubuntu<br>
(though it would be nice to have Calc for editing dbf).<br>
--<br>
<br>
Postgis:<br>
osm_local 38 MB<br>
osm_local_merc 37 MB<br>
pgrouting 181 MB<br>
sahana 21 MB<br>
mapbender 15 MB<br>
52nSOS 20 MB<br>
natural_earth 69 MB<br>
<br>
Aside from asking pgrouting to use the same OSM dump (not sure if they<br>
switched from their premade sample) postgis seems ok on space usage.<br>
--<br>
<br>
Packages:<br>
<br>
libboost1.42-dev 69 M <- Is this necessary after boost packages are<br>
built? maybe we need better cleanup after boost stuff.<br>
<br>
gnome-user-guide 52 M <- Xubuntu, why do we need gnome stuff?<br>
<br>
smbclient 42.6 M <- does the live disc need to be able to browse windows<br>
shares? I can see the value of this for the vm.<br>
<br>
openjdk-6-jdk 35 M <- is the dev kit required or is jre sufficient?<br>
<br>
oxygen-icon-theme 31 M <- looks like elementary icon is the defualt so<br>
drop this<br>
humanity-icon-theme 20.3 M <- same<br>
<br>
Looks like that's a 200+ MB savings 100 MB on the ISO, quite good for<br>
quick look.<br>
<br>
For now the following seems safe to tack in the setdown.sh<br>
apt-get remove oxygen-icon-theme humanity-icon-theme gnome-user-guide<br>
libboost1.42-dev<br>
<br>
Language packs are another place to look after that, but I'm hesitant to<br>
have to decide between languages. They also only looks like 8 MB a piece<br>
which doesn't seem right to me - can any non-english users confirm the<br>
presence of and usability of language selection (ex, does firefox load<br>
in the chosen language)?<br>
<br>
TODO: For 5.5 try to get all the Java packages onto one JRE.<br>
<br>
I think the base Xubuntu is in the 1.5-2 GB range, though I will confirm.<br>
--<br>
<br>
/usr/local 2.5 GB<br>
/usr/share 1.6 GB<br>
/usr/lib 2.7 GB<br>
Tot 7.2<br>
<br>
/usr/local/share/gisvm 188 M<br>
/usr/local/share/data 765 M<br>
<br>
/usr/local/share/data/north_carolina 435 M<br>
/usr/local/share/data/natural_earth 249 M<br>
<br>
Seems like those last 2 are bigger than we expected 684 M before<br>
compression, likely 342 M on the ISO.<br>
<br>
I believe we need to keep some of the NC dataset, there was talk<br>
specifically of hi res rasters and lidar which a few apps do want to use<br>
and might already be. That doesn't mean we need everything though.<br>
<br>
Towns as a tif seem kinda odd, wouldn't it be more common to use a<br>
vector for that or show people how to convert it to raster for analysis<br>
purposes, etc.. (maybe I'm getting nit picky).<br>
--<br>
<br>
I see and easy 200-300 MB (100-150 on the ISO) of things we can pick<br>
off. Should put us back closer to the goal.<br>
<br>
Now to figure out why the beta4 iso is 100 MB more than the beta3 (I<br>
suspect it was Xubuntu updates)...<br>
<br>
Thanks,<br>
