Description
I can remove a bit of duplication & free up a bit of disc space by writing an import script to load in the NC 2008 dataset into grass as a first step in the quick start.
perhaps another to import the Natural Earth data, although that one is targeted for cartography and may mostly be useful in teaching exercizes in how to clean up topology in dirty datasets. :-)

ps- since -all- changes to the OS are saved in user-space on the usb, having only 200mb free might fill things up in just a week or two of use.

Natural Earth 2 has substantially improved topological consistency - could be verified with GRASS

Just FYI, meanwhile import from web sites is as simple as this:
# define variable with URL and special GDAL/OGR driver INFILE="/vsizip/vsicurl/https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_0_countries.zip" # import and check/fix topology v.import input=$INFILE output=country_boundaries
Done.

will be limited to imagery and floating point raster data, which is good because they are generally big files which don't compress well.
I tried other categorical raster and vector (+dbf) but the shapefiles are lossy. fortunately those compress rather well so don't hog the disc space as much.
things like slope,aspect,shaded-relief can be regenerated on the fly from original sources, so can be dropped in favour of a regeneration script.
