Another important reason is that netbase doesn't start in all runlevels.  So
if you start in single user mode, you have the network, but no spoof
protection.  That's not too dangerous since you don't have any services
running either, but it's a silly risk.

Anyone who looks into reorganizing the network config should take a look at
what runlevels things are at (rcS versus rc[12345]).  If network interfaces
are configured at boot (in rcS), spoof protection, dhcp, bootp, routed, etc
should probably all be in rcS as well.
