Comment (by rhaas):
The command (from the secure-delete package) {{{ sfill -l -l -z -v / # two -l }}} might be useful to fill empty blocks on the hard disk with zeroes to improve compressability. Using this lets me compress a (used, with some extra packages like atlas-base-dev, scite, VisIt [which is 400MB], maybe others) virtual machine disk down to 1.2GB which is not that much larger than the original size of 1.1GB. My raw hard disk image is 8GB so I guess I must have increased it at one point to make room for eg. VisIt.
It might also help (while we are all testing this), to just put the uncompressed file at a file system location at LSU so that those who have LSU accounts (all of us I think) can use rsync to do an efficient update of our "local copy".
