1. Feature: for flexibility reasons and as a prerequisite to clean
shutdowns, allow the configuration of a stop/shutdown command
via rc.conf variable "jail_<name>_exec_stop" in addition to the
start/boot command (rc.conf variable "jail_<name>_exec_start"). For
backward compatibility reasons, rc.conf variable "jail_<name>_exec"
is still supported, too.
2. Debug: Add the used boot/shutdown commands to the debug output of
the /etc/rc.d/jail script, too.
3. Security: Run the Jail start/boot command in a cleaned environment
to not leak information from the host to the Jail during startup.
4. Feature: Run the Jail stop/shutdown command "jail_<name>_exec_stop" on
"/etc/rc.d/jail stop <name>" to allow a graceful shutdown of the Jail
before its processes are just killed.
5. Bugfix: When killing the remaining Jail processes give the processes
time to actually perform their termination sequence. Without this the
subsequent umount(8) operations usually fail because the resources
are still in use. Additionally, if after trying to TERM-inate the
processes there are still processes hanging around, finally just KILL
them.
6. Bugfix: In rc.shutdown, if running inside a Jail, skip the /etc/rc.d/*
scripts which are flagged with the KEYWORD "nojail" to allow the
correct operation of rc.shutdown under jail_<name>_exec_stop="/bin/sh
/etc/rc.shutdown". This is analogous to what /etc/rc does inside a Jail.
Now the following typical host-configuration for two Jails works as
expected and correctly boots and shutdowns the Jails:

These can be used to pass extra options to the mdmfs(8) utility,

Use these two new flags to mount tmpmfs and varmfs without

To start/stop/check on a specific device give the device name as
the second argument to the script:
# /etc/rc.d/moused start ums0
To use different rc.conf(5) knobs with different mice use the device
name as part of the knob. For example, if the mouse device is ums0, then:
moused_ums0_enable=yes
moused_ums0_flags="-z 4"
moused_ums0_port="/dev/ums0"
Starting rc.d/moused without the device argument will use the standard
moused_* flags. So, this commit should not disrupt or change current usage.
To preserve current behaviour with respect to usb mice, which appear
automatically when inserted, there is a new knob, moused_nondefault_enable,
which will treat any devices without rc.conf knobs as enabled.
To minimize knobs in /etc/rc.conf, the device file and pid file are
auto-computed, so that in the typical case for a usb mouse you don't
need to add anything extra in /etc/rc.conf to get it working.
Additionally, this updates /etc/usbd.conf to use the rc.d/moused script so
people don't have to modify it to configure their usb mouse anymore.

1. Making the pid symlink now has to happen after named starts, otherwise
it can generate a fatal error.
2. named-xfer is not part of the BIND 9 world.
3. BIND 9 needs a /dev/random in the chroot directory if chrooted.
4. Only the pid file is symlinked now, the ndc socket is BIND 8 only.
5. Create an rndc.key file for the user if one does not exist.
This (generally) allows a BIND 8 config file to be used in a BIND 9
world with little or no modification.
Without this change, if one had a swap-on-mirror configuration, gmirror

accurate. This removes the nasty hackery in rc.d/ntpdate that would parse
out ntp servers from /etc/ntp.conf (ntpd knows how to read its own config
file). By default, ntpd *will* sync with its listed time servers. To
turn this off so that ntpd does not sync, ntpd_sync_on_start="NO" can be
added to /etc/rc.conf. If ntpd is not enabled (the default), then time is
not synced on startup. ntpdate has been depreciated by the ntpd authors

o Separate out local (ports) scripts that use rc.d, and the old style
startup/shutdown scripts and execute them separately. On startup the
rc.d style scripts are executed first and then the old-style scripts.
On shutdown, exactly the reverse happens.
o The rc.d ports scripts should now behave more like base system scripts.
Scripts ending in .sh will be sourced into the current shell, while the
rest will be executed in a subshell. Previously, all ports scripts,
regardless of the .sh suffix, were executed in a subshell.
o The parent script, /etc/rc.d/localpkg, passes its command line arguments
straight to the rc.d ports scripts. This means they should now honor
faststop and faststart commands as well. Old style scripts, should not see
any differences. They will still get either a start or stop command.
o The initial phrase shown during shutdown has been changed to use
"local packages" instead of "daemon processes" to be more inline with the
phrase used during local package startup. The phrases are also used only for
old-style ports script startup/shutdown, whereas previously they were being
used for both rc.d and old-style scripts. This should make startup/shutdown
output a bit less ugly.

ip6addrctl_enable is set to YES, address selection policy is installed

If there is /etc/ip6addrctl.conf, it is used for address selection
policy. Even if there is no /etc/ip6addrctl.conf, we install default
policy. In this case, if ipv6_enable is set to YES, we use address
selection policy described in RFC 3484 as default. Otherwise, we
install priority policy for IPv4 address.
The default of ip6addrctl_enable is NO for now. However, it may
better to enable it by default.
The reason for doing this is that (at least some) 4.x binaries are very
unhappy if host.conf does not exist, and if we create host.conf but not

is better to create a correct nsswitch.conf right away.
