since 6.39rc33 we have the possibility to run scripts upon DHCP client acquires/releases an address, and certain local variables get populated with actual values.
it would be nice to have all received options inserted into individual variables, like $option43 or as an associative array, where the array index would be a number, like 43 for option 43.
and of course the same should be implemented for ipv6 as well.
this way we could have access to all options without further ROS feature integration.
