We no longer do /etc/hostname.* files, we do /etc/ifconfig.* files
instead, which contain lines each of which is fed to
ifconfig in turn. A new variable, net_interfaces, controls which
interfaces get brought up, by default, ifconfig -l is used to find a list.
the new /etc/rc.conf. this also includes the following changes:
netstart: ifaliases now includes a netmask, to ensure
aliases work.
rc/rc.local: make _everything_ based on configuration
in rc.conf. also move things around such that DNS and
YP are started early enough that other daemons needing
their services also exist. move ldconfig from rc.local
here, and also make it use /etc/ld.so.conf if it exists.
run /etc/rc.lkm if it exists, a boot time.
