OK, then please either _change_ it to <use-nanny>true</use-nanny>,
e.g. using:

  old /etc/wicked/common.xml
  sed -e 's|<use-nanny>false</use-nanny>|<use-nanny>true</use-nanny>|g' -i
/etc/wicked/common.xml

or create a local.xml containing it:

  printf "<config>\n\t<use-nanny>true</use-nanny>\n</config>\n" >
/etc/wicked/local.xml

both commands have to be executed as root of course.

Then verify that the file is changed:

  grep use-nanny /etc/wicked/*.xml

and contains a <use-nanny>false</use-nanny> now,
then restart wickedd and reapply the configs:

 rcwickedd restart # note: wickedd with 2 * d here
 wicked ifup all

or reboot.
