Either way.  This isn't very important to me.

Another option would be to have a single string option for additional
static routes, which is then parsed in network_support.c.

It's an interesting problem.  As other writers have pointed out,
there's a case for taking this out of the kernel configuration
altogether.  For my project I'm now intending to use the ioctl()s
directly, and never call init_all_network_interfaces().
