It is not solution - it is workaround=20
  - I do not wand any dhcp activity if I have no media (say in car)
    And dhclient in case of failure of detecting network address will
    install lask seen one, with last seen default gateway and I will get
    very long timeout while any of my apps will try to reach network
    instead of instant 'no route to host'
