Omaha #3049 - entire data directory cannot be removed because it is mounted

The script does still verify that the variable reference to the data directory is set. Thus, the root
directory could only be removed as a result of malicious intent. A user could intentionally not
set the data directory and remove the verification check or the user could intentionally set the
data directory to the root location.
