Presently, ifconfig callbacks are used for L2 configuration, media
and vlan, so actions associated with address assignment, like sending
out a gratuitous ARP, should go when L2 is running already.
This also should fix the problem with setting up vlan interfaces
from rc.conf, when both IP and vlan+vlandev parameters are passed
to ifconfig at once.
Future work: Consider introducing several ifconfig callback lists
to invoke callbacks orderly.

/tmp may not be writeable yet when dhclient is first run via
/etc/rc.d/netif so using it may not work. Also, writing to a
predictable file in /tmp as root is a really bad idea since a malicious
user may be able to win a race and insert a symlink which will allow
them to cause any file to be overwritten. To solve these problems,
create the tempory file in /var/run which will exist this early and is
writable only by root.
Security: Local risk if users can cause dhclient to run on demand
(such as by unplugging and replugging the network cable).
system is mounted. This prevevents duplicated mounts.
The change I made against the original patch is to fall back to the given
path on realpath(2) failure instead of exiting with an error.

entries from the interface rather than using ifconfig's delete command.
This preserves non-dhclient configured addresses (though they are wiped
out when dhclient is restarted).

disk. Apparently some people want to use mdmfs as mount_* as a
shortcut for mounting existing file-based file systems.
Note that unlike in the patches from the submitters, this option is
not available in compat mode. Compat mode was supposed to support only
things that mount_mfs used to support. To use this option from fstab,
mdmfs should be called mount_md, not mount_mfs. This distinction has
not always upkept for new options, and those can't be fixed now
without breaking people's systems, but new options should not usually
be allowed in compat mode. (Not sure why -F is allowed there at all.)

autonumbering is requested, set the unit to 0 instead of -1. This

kernel is in the order the devices were made, which is not useful to
the user. Also, remove the "%d more" test since the kernel does not
return the complete count in md_pad[0] (maybe it should?).
