So do I, but why is flushroutes true out of the box?  Isn't that
the right thing to fix?

I still don't see why "root on NFS" is the right condition to use in a
test for whether to flush routes or to change the default route.  For
example, if root is local but /var is on NFS, you will get similar
problems.  Perhaps a better test would be that dhcpcd shouldn't touch
the default route unless the default route is through the interface that
dhcpcd is managing.
