Actually I have something to add about /etc/rc.conf.d and it's not
about the shell code.
My purpose to all this was to find a way to configure network
interfaces that doesn't require parsing rc.conf. We deploy hundreds of
machines using data center management tools so writing functions in
these tools for network configuration becomes much easier if you
separate the network configuration into their own files.
So using /etc/rc.conf.d/network will work, but I would like to go
further and suggest the OpenBSD model of using interface.ifname or
something similar. One file for each interface that is.
