This script lets you export any directory you like from a virtual
machine as a tarball. For example, to export
from a standard Fedora or RHEL virtual machine you would do:
export2tar.sh guest.img /dev/VolGroup00/LogVol00 /home home.tar.gz
/dev/VolGroup00/LogVol00 is the partition or LV inside
the VM which contains the directory you want.
