Mnesia is able to detect it during the "handshake" after restart.
It then generates an event, 
{inconsistent_database, running_partitioned_network, Node}.

One may argue that when mnesia reports this, it's a bit late,
since damage may already have been done. This is why we started
using -kernel dist_auto_connect_once. If the nodes cannot 
automatically re-connect, you can detect partitioned networks
"out-of-band".

What we did with this information was to write to a special
file on disk. This information is then read during restart.
