Using this option, default string values that are
configurable are printed as unconfigured values,
e.g. "@CONFDIR@" instead of "/etc".

 Version 2.02.119 - 
 ==================================
+  Add --unconfigured option to dumpconfig to print strings unconfigured.
   Add --withfullcomments option to dumpconfig to print full comment.
   Check for lvm binary in blkdeactivate and skip LVM processing if not present.
   Add --enable-halvm and --disable-halvm options to lvmconf script.
