Actually I want to do it like ipfail: if node A cannot reach
the ping_nodes, check if node B can, if it cannot, then
leave services running on node A. if node B can
reach the ping_nodes then failover.
Only, that I'm not checking with ping but the physical
link, and so I need a way to get the information from
the other node ("link status"). So have to figure out

This is what ipfail uses, maybe I have to take a closer look.
