DESCRIPTION
     Reset-Machine-ID  resets  the  machine  identity  state, particularly for a
     cloned VM, to make it appear as a new machine.  It performs  the  following
     tasks:
     *	 Reset /etc/machine-id
     *	 Reset /var/lib/dbus/machine-id (symlink to /etc/machine-id)
     *	 Reset	host  ID in Debian Popularity Contest configuration file (if in-
	 stalled)
     *	 Change hostname, if a new one is provided (--hostname parameter)
     *	 Provide hardened settings for SSH client and server
     *	 Create new SSH key pair
     The  changes  are	made  interactively  on  request,  unless   the   option
     --yes-to-all-i-am-really-sure is used.

ARGUMENTS
     The following options are available:

     -H hostname | --hostname hostname
	     Set the given hostname.

     -M | --skip-machine-id
	     Do not reset the machine ID.

     -S | --skip-ssh-configuration
	     Do not make SSH configuration changes.

     -K | --skip-ssh-key-replacement
	     Do not replace SSH keys.

     -Z zabbix_server | --zabbix zabbix_server
	     Configure	an  already-installed  Zabbix  Agent  for a given Zabbix
	     server.

     -A | --install-zabbix-agent
	     Try to install Zabbix Agent, if necessary, when a Zabbix server  is
	     given  but  no Zabbix Agent is installed. This will add the current
	     Zabbix PPA on Debian/Ubuntu/Fedora systems. Note that a Zabbix  PPA
	     may  not  be  available  for the used distribution! On FreeBSD, the
	     Zabbix Agent is installed from the FreeBSD Ports Collection.

     --yes-to-all-i-am-really-sure
	     Create new keys (delete old ones) as well	as  replace  sshd_config
	     and ssh_config without interactively asking for confirmation.

     -h | --help
	     Prints the program's command-line parameters and exits.

     -v | --version
	     Prints the program version and exits.

EXIT STATUS
     The Reset-Machine-ID tool exits with 0 on success, and >0 in case of an er-
     ror.
