Yes I use a rule of thumb 50%. So 200 MB in the OS tends to be 100MB in
the ISO. This has been fairly true for all of our builds in the past
though currently we're shrinking 9.8 to 3.8 which is more than 50%
savings. The nice part is if you don't go down to the individual file
level it seems to average out compressible vs non.

Inkscape is being used in Cartography these days (I should know I did a
class with it last year and my friend is giving a talk about it at
FOSS4G). I believe we already removed gimp, and OOo was never on Xubuntu
(though it would be nice to have Calc for editing dbf).

Postgis:
osm_local 38 MB
osm_local_merc 37 MB
pgrouting 181 MB
sahana 21 MB
mapbender 15 MB
52nSOS 20 MB
natural_earth 69 MB

Aside from asking pgrouting to use the same OSM dump (not sure if they
switched from their premade sample) postgis seems ok on space usage.

Packages:

libboost1.42-dev  69 M <- Is this necessary after boost packages are
built? maybe we need better cleanup after boost stuff.

gnome-user-guide 52 M <- Xubuntu, why do we need gnome stuff?

smbclient 42.6 M <- does the live disc need to be able to browse windows
shares? I can see the value of this for the vm.

openjdk-6-jdk 35 M <- is the dev kit required or is jre sufficient?

oxygen-icon-theme 31 M <- looks like elementary icon is the defualt so
drop this
humanity-icon-theme 20.3 M <- same

Looks like that's a 200+ MB savings 100 MB on the ISO, quite good for
quick look.

For now the following seems safe to tack in the setdown.sh
apt-get remove oxygen-icon-theme humanity-icon-theme gnome-user-guide
libboost1.42-dev

Language packs are another place to look after that, but I'm hesitant to
have to decide between languages. They also only looks like 8 MB a piece
which doesn't seem right to me - can any non-english users confirm the
presence of and usability of language selection (ex, does firefox load
in the chosen language)?

TODO: For 5.5 try to get all the Java packages onto one JRE.

I think the base Xubuntu is in the 1.5-2 GB range, though I will confirm.
--

/usr/local 2.5 GB
/usr/share 1.6 GB
/usr/lib 2.7 GB
Tot 7.2

/usr/local/share/gisvm 188 M
/usr/local/share/data 765 M

/usr/local/share/data/north_carolina 435 M
/usr/local/share/data/natural_earth 249 M

Seems like those last 2 are bigger than we expected 684 M before
compression, likely 342 M on the ISO.

I believe we need to keep some of the NC dataset, there was talk
specifically of hi res rasters and lidar which a few apps do want to use
and might already be. That doesn't mean we need everything though.

Towns as a tif seem kinda odd, wouldn't it be more common to use a
vector for that or show people how to convert it to raster for analysis
purposes, etc.. (maybe I'm getting nit picky).

I see and easy 200-300 MB (100-150 on the ISO) of things we can pick
off. Should put us back closer to the goal.

Now to figure out why the beta4 iso is 100 MB more than the beta3 (I
suspect it was Xubuntu updates)...

Thanks,
Alex
