Is there some way one can reset all unused sectors on the disk to only
contain 0xFF or Ox00?
That would make the image file compressible to a few GB and possible
to share.
On this wiki page:
http://wiki.freepascal.org/Small_Virtual_Machines
I show:
sudo dd if=/dev/zero of=/mytempfile (this is very slow as it fills
the entire partition)
sudo rm -f /mytempfile
That last step is a little dangerous as my Linux student friends at Ohio
State have a similar example that they like to point out. :)
Also, I'm not sure what exactly it does so you should research it more
before doing it!
