NetBSD/etc/netstart
mrg 3b98afb4c5 move start-time configuration from netstart, rc, rc.local into
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.

# has a "destination" (i.e. it's a point-to-point link, like SLIP).
# dest_addr is the hostname of the other end of the link, in /etc/hosts
#
# the only required contents of the file are the addr_family field
