  Comparing disklayout generated before and after. Here is the difference:

 # Format for LVM LVs
 # lvmvol <volume_group> <name> <size(bytes)> <layout> [key:value ...]
 # WARNING: Volume rhel_ibm-p9wr-08/home has multiple segments. Restoring it in Migration Mode using 'lvcreate' won't preserve segments and properties of the other segments as well!

• Brief description of the changes in this pull request:
  Minor adjustments to Issue #2187 - disklayout.conf file contains duplicate lines #2194. Do not overload the kval variable - intended for passing options to lvcreate - by adding extra keys to it, which are not supported by lvcreate. Introduce another variable infokval for this purpose and print those unsupported and purely informational keys only in comments.
