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".
