re-add $ipv6_enable support for backward compatibility. From
UPDATING:
1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF
for IPv4. For aliases, $ifconfig_IF_aliasN should be used.
Note that both variables need the "inet6" keyword at the head.
Do not set $ipv6_network_interfaces manually if you do not
understand what you are doing. It is not needed in most cases.
$ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but
they are obsolete.
2. $ipv6_enable is obsolete. Use $ipv6_prefer and/or
"inet6 accept_rtadv" keyword in ifconfig(8) instead.
If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and
all configured interfaces have "inet6 accept_rtadv" in the
$ifconfig_IF_ipv6. These are for backward compatibility.
3. A new variable $ipv6_prefer has been added. If NO, IPv6
functionality of interfaces with no corresponding
$ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag,
and the default address selection policy of ip6addrctl(8)
is the IPv4-preferred one (see rc.d/ip6addrctl for more details).
Note that if you want to configure IPv6 functionality on the
disabled interfaces after boot, first you need to clear the flag by
using ifconfig(8) like:
ifconfig em0 inet6 -ifdisabled
If YES, the default address selection policy is set as
IPv6-preferred.
The default value of $ipv6_prefer is NO.
4. If your system need to receive Router Advertisement messages,
define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8)
scripts automatically invoke rtsol(8) when the interface becomes
UP. The Router Advertisement messages are used for SLAAC
(State-Less Address AutoConfiguration).
network_ipv6->rc.d/netif integration:
- $ipv6_enable is now obsolete. Instead, IPv6 is enabled by
default if the kernel supports it, and $ipv6_network_interfaces
is "none" by default. If you want to use IPv6, define
$ipv6_network_interfaces and $ifconfig_xxx_ipv6.
An interface which is in $network_interfaces and not in
$ipv6_network_interfaces will be marked as "inet6
-auto_linklocal ifdisabled" (see ifconfig(8)).
- $ipv6_ifconfig_xxx is renamed to ifconfig_xxx_ipv6 for
consistency with other address families. The old variables
still work but can be removed in the future. Note that
ipv6_ifconfig_xxx="..." should be replaced with
ifconfig_xxx_ipv6="inet6 ...".
- Receiving ICMPv6 Router Advertisement is not automatically
enabled even if there is no manual configuration of IPv6 in
rc.conf. If you want it, define
ifconfig_xxx_ipv6="inet6 ... accept_rtadv".
- The rc.d/ip6addrctl now chooses address selection policy based
on $ipv6_prefer, not $ipv6_enable. The default is
ipv6_prefer=NO.
- $router* and $ipv6_router* are replaced with $routed_* and
$route6d_* for consistency. The old variables still work but
can be removed in the future.

statically bind IPv4 <-> MAC address at boot time.
In order to use this, the administrator needs to configure the following
rc.conf(5) variable:
- static_arp_pairs: A list of names for static bind pairs, and,
- a series of static_arp_(name): the arguments that is being passed to
``arp -S'' operation.
Example:
static_arp_pairs="gw"
static_arp_gw="192.168.1.1 00:01:02:03:04:05"
See the rc.conf(5) manual page for more details.

using freebsd-update. This applies to using freebsd-update in "upgrade
mode" and normal freebsd-update on a security branch.
The backup kernel will be written to /boot/kernel.old, if the directory
does not exist, or the directory was created by freebsd-update in a
previous backup. Otherwise freebsd-update will generate a new directory
name for use by the backup. By default symbol files are not backed up
to save diskspace and avoid filling up the root partition.
This feature is fully configurable in the freebsd-update config file,
but defaults to enabled.

2. New feature: option to create a forwarder configuration file based on
the contents of /etc/resolv.conf. This allows you to utilize a local
resolver for better performance, less network traffic, custom zones, etc.
while still relying on the benefits of your local network resolver.

3. Add named-checkconf into the startup routine. This will prevent named

Note: this is only really necessary because of the ifconfig
logic to add/remove the jail IPs upon start/stop.
Consensus among simon and I is that the logic should
really be factored out from the startup script and put
into a proper management solution.
- We now support starting of no-IP jails.
- Remove the global jail_<jname>_netmask option as it is only
helpful to set netmasks/prefixes for the right address
family and per address.
- Implement jail_<jname>_ip options to support both
address familes with regard to ifconfig logic.
- Implement _multi<n> support suffix to the jail_<jname>_ip
option to configure additional addresses to avoid overlong,
unreadbale jail_<jname>_ip lines with lots of addresses.
