                    active cloning mode options.

WARNING:

You probably don't want to invoke this utility directly. It will reset ALL
global instance-specific data on this machine, including but not limited to
passwords, certificates, and optionally license keys.

If you are preparing a public master image for a cloud platform or
virtualization solution take a look at 'cloning' utility.

If you are sure you need to invoke this utility directly, pass --do-what-I-say
option. Note that this utility is not designed to reset any customer data, but
only global and admin data.
