I have a static unreachable route configured in /etc/sysconfig/network/routes.
The network is brought up with wicked. It seems that at some point it stopped
picking up unreachable or blackhole routes.

The contents of /etc/sysconfig/network/routes are:

0.0.0.0/0 - - - table next0 type unreachable metric 127

I tried moving it into /etc/sysconfig/network/ifroute-eth0, but it did not
change anything, 'ip route show table next0' still does not show the
unreachable route. 

Adding it manually works fine.
