I have Ubuntu installed in a VMware virtual machine, which is just a collection of disk files, the largest of which is the disk image.
I want to make a tarball of these files of minimal size. This seems to require erasing the contents of the unused areas of the virtual ext3 filesystem, so they will compress optimally. Is there some standard utility that will do this? Note this is not a "data security erase" problem where the unused sectors are to be repeatedly overwritten with different bit patterns; I just want to clear them once to binary zeros.
