on aggregate that's ok, but for geodata it is probably too crude
to go by. LiDAR data will probably compress 85%, OSM XML data
compresses by similar margins. But MrSID geotiffs won't compress
at all..

> Inkscape is being used in Cartography these days

I know, thus the pain in considering what to remove.

> I believe we already removed gimp,

yes AFAIR, I more mean that class of not-strictly geo packages
but still really useful for the end user for them to be there.
e.g. maybe replace the email client with Slypheed, etc..

we probably want a media player for YouTube or other video
quickstarts....

etc

I think we ship Gnumeric which I think covers that.
(yay dbview)

is the reprojected version strictly necessary?

a little ouch, but if it compresses well, probably not a big
worry.

acceptable imo

most likely not, and if it is there probably boost docs -dev
and a couple hundred MB of other boost -dev packages are also
there (it's a real beast). Will need to study the latest build
log to see where that gets left behind. (perhaps [my] gpsdrive
dep?)

gtk programs still there, but I doubt we need to keep that.

.. and for workshops with tutorial data held on a central
server. but is smbclient just the command line ftp-like
interface or is it the backend lib? If smb client access still
works via Thunar or Konquerer or whatever maybe we don't need it?

what needs that and not Sun's version?

> humanity-icon-theme 20.3 M <- same

good .. but does anything important depend on them?
(ie does 'apt-get remove' want to take away the kitchen sink
as well?)

it should be done in setup.sh just after gimp, xscreensaver, etc
are removed.

> libboost1.42-dev

let the install script which sucked that in remove it.
(if removal is applicable)

IIRC a base VM comes in about 2.2gb after install & updates.

forget the rule of thumb for those, just look at the size
of the .zip files they came from. (about 100mb and 60mb
respectively IIRC)

well if we want folks to move to a common dataset, the earlier
we start shipping it the better. :)

sorry, which layer exactly is that? I assume any geotiff is
imagery data, ... a quick spin through qgis should answer that,
maybe just an unobvious name?

check that an old linux kernel image and headers are not there,
$ dpkg -l | grep linux-image | grep ^ii

?
