NAME
rc.conf -- system configuration information
DESCRIPTION
The file rc.conf contains descriptive information about the local host
name, configuration details for any potential network interfaces and
which services should be started up at system initial boot time. In new
installations, the rc.conf file is generally initialized by the system
installation utility, sysinstall(8).
The purpose of rc.conf is not to run commands or perform system startup
actions directly. Instead, it is included by the various generic startup
scripts in /etc which conditionalize their internal actions according to
the settings found there.
The /etc/rc.conf file is included from the file /etc/defaults/rc.conf,
which specifies the default settings for all the available options.
Options need only be specified in /etc/rc.conf when the system adminis-
trator wishes to override these defaults. The file /etc/rc.conf.local is
used to override settings in /etc/rc.conf for historical reasons. See
the rc_conf_files variable below.
Options are set with ``name=value'' assignments that use sh(1) syntax.
The following list provides a name and short description for each vari-
able that can be set in the rc.conf file:
rc_debug (bool) If set to ``YES'', enable output of debug messages
from rc scripts. This variable can be helpful in diagnosing
mistakes when editing or integrating new scripts. Beware
that this produces copious output to the terminal and
syslog(3).
rc_info (bool) If set to ``NO'', disable informational messages from
the rc scripts. Informational messages are displayed when a
condition that is not serious enough to warrant a warning or
an error occurs.
early_late_divider
(str) The name of the script that should be used as the
delimiter between the ``early'' and ``late'' stages of the
boot process. The early stage should contain all the ser-
vices needed to get the disks (local or remote) mounted so
that the late stage can include scripts contained in the
directories listed in the local_startup variable (see below).
Thus, the two likely candidates for this value are mountcrit-
local for the typical system, and mountcritremote if the sys-
tem needs remote file systems mounted to get access to the
local_startup directories; for example when /usr/local is NFS
mounted. For rc.conf within a jail(8) NETWORKING is likely
to be an appropriate value. Extreme care should be taken
when changing this value, and before changing it one should
ensure that there are adequate provisions to recover from a
failed boot (such as physical contact with the machine, or
reliable remote console access).
swapfile (str) If set to ``NO'', no swapfile is installed, otherwise
the value is used as the full pathname to a file to use for
additional swap space.
apm_enable (bool) If set to ``YES'', enable support for Automatic Power
Management with the apm(8) command.
apmd_enable
(bool) Run apmd(8) to handle APM event from userland. This
also enables support for APM.
apmd_flags (str) If apmd_enable is set to ``YES'', these are the flags
to pass to the apmd(8) daemon.
devd_enable
(bool) Run devd(8) to handle device added, removed or unknown
events from the kernel.
kldxref_enable
(bool) Set to ``NO'' by default. Set to ``YES'' to automati-
cally rebuild linker.hints files with kldxref(8) at boot
time.
kldxref_clobber
(bool) Set to ``NO'' by default. If kldxref_enable is true,
setting to ``YES'' will overwrite existing linker.hints files
at boot time. Otherwise, only missing linker.hints files are
generated.
kldxref_module_path
(str) Empty by default. A semi-colon (`;') delimited list of
paths containing kld(4) modules. If empty, the contents of
the kern.module_path sysctl(8) are used.
pccard_enable
(bool) If set to ``YES'', enable PCCARD support at boot time.
pccard_mem (str) Set to PCCARD controller memory address or ``DEFAULT''
for the default value.
pccard_beep
(int) If 0, set the PCCARD controller to silent mode. If 1,
set it to beep mode. If 2, set it to melody mode.
pccard_conf
(str) Path to the configuration file for the pccardd(8) dae-
mon (e.g. /etc/pccard.conf.sample).
pccardd_flags
(str) If pccard_enable is set to ``YES'', these are the flags
to pass to the pccardd(8) daemon.
powerd_enable
(bool) If set to ``YES'', enable the system power control
facility with the powerd(8) daemon.
powerd_flags
(str) If powerd_enable is set to ``YES'', these are the flags
to pass to the powerd(8) daemon.
tmpmfs Controls the creation of a /tmp memory file system. Always
happens if set to ``YES'' and never happens if set to ``NO''.
If set to anything else, a memory file system is created if
/tmp is not writable.
tmpsize Controls the size of a created /tmp memory file system.
tmpmfs_flags
Extra options passed to the mdmfs(8) utility when the memory
file system for /tmp is created. The default is ``-S -M'',
which inhibits the use of softupdates on /tmp to waste as
little space as possible and creates a pure memory backed
disk, which will never be swapped out, for maximum perfor-
mance and system stability at low memory conditions. See
mdmfs(8) for other options you can use in tmpmfs_flags.
varmfs Controls the creation of a /var memory file system. Always
happens if set to ``YES'' and never happens if set to ``NO''.
If set to anything else, a memory file system is created if
/var is not writable.
varsize Controls the size of a created /var memory file system.
varmfs_flags
Extra options passed to the mdmfs(8) utility when the memory
file system for /var is created. The default is ``-S -M'',
which inhibits the use of softupdates on /var to waste as
little space as possible and creates a pure memory backed
disk, which will never be swapped out, for maximum perfor-
mance and system stability at low memory conditions. See
mdmfs(8) for other options you can use in varmfs_flags.
populate_var
Controls the automatic population of the /var file system.
Always happens if set to ``YES'' and never happens if set to
``NO''. If set to anything else, a memory file system is
created if /var is not writable. Note that this process
requires access to certain commands in /usr before /usr is
mounted on normal systems.
cleanvar_enable
(bool) Clean the /var directory.
local_startup
(str) List of directories to search for startup script files.
script_name_sep
(str) The field separator to use for breaking down the list
of startup script files into individual filenames. The
default is a space. It is not necessary to change this
unless there are startup scripts with names containing spa-
ces.
hostapd_enable
(bool) Set to ``YES'' to start hostapd(8) at system boot
time.
hostname (str) The fully qualified domain name (FQDN) of this host on
the network. This should almost certainly be set to some-
thing meaningful, even if there is no network connection. If
dhclient(8) is used to set the hostname via DHCP, this vari-
able should be set to an empty string.
ipv6_enable
(bool) Enable support for IPv6 networking. Note that this
requires that the kernel has been compiled with options
INET6.
nisdomainname
(str) The NIS domain name of this host, or ``NO'' if NIS is
not used.
dhclient_program
(str) Path to the DHCP client program (/sbin/dhclient, the
OpenBSD DHCP client, is the default).
dhclient_flags
(str) Additional flags to pass to the DHCP client program.
For the OpenBSD DHCP client, see the dhclient(8) manpage for
a description of the command line options available.
background_dhclient
(bool) Set to ``YES'' to start the DHCP client in background.
This can cause trouble with applications depending on a work-
ing network, but it will provide a faster startup in many
cases.
firewall_enable
(bool) Set to ``YES'' to load firewall rules at startup. If
the kernel was not built with options IPFIREWALL, the ipfw.ko
kernel module will be loaded. See also ipfilter_enable.
ipv6_firewall_enable
(bool) The IPv6 equivalent of firewall_enable. Set to
``YES'' to load IPv6 firewall rules at startup. If the ker-
nel was not built with options IPV6FIREWALL, the ip6fw.ko
kernel module will be loaded.
firewall_script
(str) This variable specifies the full path to the firewall
script to run. The default is /etc/rc.firewall.
ipv6_firewall_script
(str) The IPv6 equivalent of firewall_script.
firewall_type
(str) Names the firewall type from the selection in
/etc/rc.firewall, or the file which contains the local fire-
wall ruleset. Valid selections from /etc/rc.firewall are:
open unrestricted IP access
closed all IP services disabled, except via ``lo0''
client basic protection for a workstation
simple basic protection for a LAN.
If a filename is specified, the full path must be given.
ipv6_firewall_type
(str) The IPv6 equivalent of firewall_type.
firewall_quiet
(bool) Set to ``YES'' to disable the display of firewall
rules on the console during boot.
ipv6_firewall_quiet
(bool) The IPv6 equivalent of firewall_quiet.
firewall_logging
(bool) Set to ``YES'' to enable firewall event logging. This
is equivalent to the IPFIREWALL_VERBOSE kernel option.
ipv6_firewall_logging
(bool) The IPv6 equivalent of firewall_logging.
firewall_flags
(str) Flags passed to ipfw(8) if firewall_type specifies a
filename.
ipv6_firewall_flags
(str) The IPv6 equivalent of firewall_flags.
natd_program
(str) Path to natd(8).
natd_enable
(bool) Set to ``YES'' to enable natd(8). firewall_enable
must also be set to ``YES'', and divert(4) sockets must be
enabled in the kernel. If the kernel was not built with
options IPDIVERT, the ipdivert.ko kernel module will be
loaded.
natd_interface
(str) This is the name of the public interface on which
natd(8) should run. The interface may be given as an inter-
face name or as an IP address.
natd_flags (str) Additional natd(8) flags should be placed here. The -n
or -a flag is automatically added with the above
natd_interface as an argument.
ipfilter_enable
(bool) Set to ``NO'' by default. Setting this to ``YES''
enables ipf(8) packet filtering.
Typical usage will require putting
ipfilter_enable="YES"
ipnat_enable="YES"
ipmon_enable="YES"
ipfs_enable="YES"
into /etc/rc.conf and editing /etc/ipf.rules and
/etc/ipnat.rules appropriately.
Note that ipfilter_enable and ipnat_enable can be enabled
independently. ipmon_enable and ipfs_enable both require at
least one of ipfilter_enable and ipnat_enable to be enabled.
Having
options IPFILTER
options IPFILTER_LOG
options IPFILTER_DEFAULT_BLOCK
in the kernel configuration file is a good idea, too.
ipfilter_program
(str) Path to ipf(8) (default /sbin/ipf).
ipfilter_rules
(str) Set to /etc/ipf.rules by default. This variable con-
tains the name of the filter rule definition file. The file
is expected to be readable for the ipf(8) command to execute.
ipv6_ipfilter_rules
(str) Set to /etc/ipf6.rules by default. This variable con-
tains the IPv6 filter rule definition file. The file is
expected to be readable for the ipf(8) command to execute.
ipfilter_flags
(str) Empty by default. This variable contains flags passed
to the ipf(8) program.
ipnat_enable
(bool) Set to ``NO'' by default. Set it to ``YES'' to enable
ipnat(8) network address translation. See ipfilter_enable
for a detailed discussion.
ipnat_program
(str) Path to ipnat(8) (default /sbin/ipnat).
ipnat_rules
(str) Set to /etc/ipnat.rules by default. This variable con-
tains the name of the file holding the network address trans-
lation definition. This file is expected to be readable for
the ipnat(8) command to execute.
ipnat_flags
(str) Empty by default. This variable contains flags passed
to the ipnat(8) program.
ipmon_enable
(bool) Set to ``NO'' by default. Set it to ``YES'' to enable
ipmon(8) monitoring (logging ipf(8) and ipnat(8) events).
Setting this variable needs setting ipfilter_enable or
ipnat_enable too. See ipfilter_enable for a detailed discus-
sion.
ipmon_program
(str) Path to ipmon(8) (default /sbin/ipmon).
ipmon_flags
(str) Set to ``-Ds'' by default. This variable contains
flags passed to the ipmon(8) program. Another typical exam-
ple would be ``-D /var/log/ipflog'' to have ipmon(8) log
directly to a file bypassing syslogd(8). Make sure to adjust
/etc/newsyslog.conf in such case like this:
/var/log/ipflog 640 10 100 * Z /var/run/ipmon.pid
ipfs_enable
(bool) Set to ``NO'' by default. Set it to ``YES'' to enable
ipfs(8) saving the filter and NAT state tables during shut-
down and reloading them during startup again. Setting this
variable needs setting ipfilter_enable or ipnat_enable to
``YES'' too. See ipfilter_enable for a detailed discussion.
Note that if kern_securelevel is set to 3, ipfs_enable cannot
be used because the raised securelevel will prevent ipfs(8)
from saving the state tables at shutdown time.
ipfs_program
(str) Path to ipfs(8) (default /sbin/ipfs).
ipfs_flags (str) Empty by default. This variable contains flags passed
to the ipfs(8) program.
pf_enable (bool) Set to ``NO'' by default. Setting this to ``YES''
enables pf(4) packet filtering.
Typical usage will require putting
pf_enable="YES"
into /etc/rc.conf and editing /etc/pf.conf appropriately.
device pf
builds pf(4) into the kernel. Otherwise it is loaded from a
module.
pf_rules (str) Path to pf(4) ruleset configuration file (default
/etc/pf.conf).
pf_program (str) Path to pfctl(8) (default /sbin/pfctl).
pf_flags (str) If pf_enable is set to ``YES'', these flags are passed
to the pfctl(8) program when loading the ruleset.
pflog_enable
(bool) Set to ``NO'' by default. Setting this to ``YES''
enables pflogd(8) which logs packets from the pf(4) packet
filter.
pflog_logfile
(str) If pflog_enable is set to ``YES'' this controls where
pflogd(8) stores the logfile (default /var/log/pflog). Check
/etc/newsyslog.conf to adjust logfile rotation for this.
pflog_program
(str) Path to pflogd(8) (default /sbin/pflogd).
pflog_flags
(str) Empty by default. This variable contains additional
flags passed to the pflogd(8) program.
pfsync_enable
(bool) Set to ``NO'' by default. Setting this to ``YES''
enables exposing pf(4) state changes to other hosts over the
network by means of pfsync(4). The pfsync_syncdev variable
must also be set then.
pfsync_syncdev
(str) Empty by default. This variable specifies the name of
the network interface pfsync(4) should operate through. It
must be set accordingly if pfsync_enable is set to ``YES''.
pfsync_ifconfig
(str) Empty by default. This variable can contain additional
options to be passed to the ifconfig(8) command used to set
up pfsync(4).
tcp_extensions
(bool) Set to ``YES'' by default. Setting this to ``NO''
disables certain TCP options as described by RFC 1323. Set-
ting this to ``NO'' might help remedy such problems with con-
nections as randomly hanging or other weird behavior. Some
network devices are known to be broken with respect to these
options.
log_in_vain
(int) Set to 0 by default. The sysctl(8) variables,
net.inet.tcp.log_in_vain and net.inet.udp.log_in_vain, as
described in tcp(4) and udp(4), are set to the given value.
tcp_keepalive
(bool) Set to ``YES'' by default. Setting to ``NO'' will
disable probing idle TCP connections to verify that the peer
is still up and reachable.
tcp_drop_synfin
(bool) Set to ``NO'' by default. Setting to ``YES'' will
cause the kernel to ignore TCP frames that have both the SYN
and FIN flags set. This prevents OS fingerprinting, but may
break some legitimate applications. This option is only
available if the kernel was built with the TCP_DROP_SYNFIN
option.
icmp_drop_redirect
(bool) Set to ``NO'' by default. Setting to ``YES'' will
cause the kernel to ignore ICMP REDIRECT packets. Refer to
icmp(4) for more information.
icmp_log_redirect
(bool) Set to ``NO'' by default. Setting to ``YES'' will
cause the kernel to log ICMP REDIRECT packets. Note that the
log messages are not rate-limited, so this option should only
be used for troubleshooting networks. Refer to icmp(4) for
more information.
icmp_bmcastecho
(bool) Set to ``YES'' to respond to broadcast or multicast
ICMP ping packets. Refer to icmp(4) for more information.
ip_portrange_first
(int) If not set to ``NO'', this is the first port in the
default portrange. Refer to ip(4) for more information.
ip_portrange_last
(int) If not set to ``NO'', this is the last port in the
default portrange. Refer to ip(4) for more information.
network_interfaces
(str) Set to the list of network interfaces to configure on
this host or ``AUTO'' (the default) for all current inter-
faces. For example, if the only active network devices in
the system are the loopback device (lo0) and a NIC using the
ed(4) driver, this could be set to ``lo0 ed0''.
An ifconfig_<interface> variable is also assumed to exist for
each value of interface. The variable can contain arguments
to ifconfig(8), as well as special case-insensitive keywords
described below. Such keywords are removed before passing
the value to ifconfig(8) while the order of the other argu-
ments is preserved.
One can configure more than one IPv4 address with the
ipv4_addrs_<interface> variable. One or more IP addresses
must be provided in Classless Inter-Domain Routing (CIDR)
address notation, whose last byte can be a range like
192.168.0.5-23/24. In this case the address 192.168.0.5 will
be configured with the netmask /24 and the addresses
192.168.0.6 to 192.168.0.23 with the non-conflicting netmask
/32 as explained in the ifconfig(8) alias section. With the
interface in question being ed0, an example could look like:
ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
It is also possible to add IP alias entries using ifconfig(8)
syntax. Assuming that the interface in question was ed0, it
might look something like this:
ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"
And so on. For each ifconfig_<interface>_alias<n> entry that
is found, its contents are passed to ifconfig(8). Execution
stops at the first unsuccessful access, so if something like
this is present:
ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff"
ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
Then note that alias4 would not be added since the search
would stop with the missing ``alias3'' entry. Due to this
difficult to manage behavior, the
ifconfig_<interface>_alias<n> form is deprecated.
If the /etc/start_if.<interface> file is present, it is read
and executed by the sh(1) interpreter before configuring the
interface as specified in the ifconfig_<interface> and
ifconfig_<interface>_alias<n> variables.
If the ifconfig_<interface> contains the keyword ``NOAUTO''
then the interface will not be configured at boot or by
/etc/pccard_ether when network_interfaces is set to ``AUTO''.
It is possible to bring up an interface with DHCP by adding
``DHCP'' to the ifconfig_<interface> variable. For instance,
to initialize the ed0 device via DHCP, it is possible to use
something like:
ifconfig_ed0="DHCP"
Also, if your interface needs WPA authentication, it is pos-
sible to add ``WPA'' to the ifconfig_<interface> variable.
Finally, you can add ifconfig(8) options in this variable, in
addition to the /etc/start_if.<interface> file. For
instance, to initialize the wi0 device via DHCP, using WPA
authentication and 802.11b mode, it is possible to use some-
thing like:
ifconfig_wi0="DHCP WPA mode 11b"
In addition to the ifconfig_<interface> form, a fallback
variable ifconfig_DEFAULT may be configured. It will be used
for all interfaces with no ifconfig_<interface> variable.
This is intended to replace the no longer supported
pccard_ifconfig variable.
It is also possible to rename interface by doing:
ifconfig_ed0_name="net0"
ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
ipv6_network_interfaces
(str) This is the IPv6 equivalent of network_interfaces.
Instead of setting the ifconfig variables as
ifconfig_<interface> they should be set as
ipv6_ifconfig_<interface>. Aliases should be set as
ipv6_ifconfig_<interface>_alias<n>. ipv6_prefix_<interface>
does something. Interfaces that do not have a
ipv6_ifconfig_<interface> setting will be auto configured by
rtsol(8) if the ipv6_gateway_enable is set to ``NO''. Note
that the IPv6 networking code does not support the
/etc/start_if.<interface> files.
ipv6_default_interface
(str) If not set to ``NO'', this is the default output inter-
face for scoped addresses. Now this works only for IPv6 link
local multicast addresses.
cloned_interfaces
(str) Set to the list of clonable network interfaces to cre-
ate on this host. Entries in cloned_interfaces are automati-
cally appended to network_interfaces for configuration.
gif_interfaces
(str) Set to the list of gif(4) tunnel interfaces to config-
ure on this host. A gifconfig_<interface> variable is
assumed to exist for each value of interface. The value of
this variable is used to configure the link layer of the tun-
nel according to the syntax of the tunnel option to
ifconfig(8). Additionally, this option ensures that each
listed interface is created via the create option to
ifconfig(8) before attempting to configure it.
sppp_interfaces
(str) Set to the list of sppp(4) interfaces to configure on
this host. A spppconfig_<interface> variable is assumed to
exist for each value of interface. Each interface should
also be configured by a general ifconfig_<interface> setting.
Refer to spppcontrol(8) for more information about available
options.
ppp_enable (bool) If set to ``YES'', run the ppp(8) daemon.
ppp_mode (str) Mode in which to run the ppp(8) daemon. Accepted modes
are ``auto'', ``ddial'', ``direct'' and ``dedicated''. See
the manual for a full description.
ppp_nat (bool) If set to ``YES'', enables network address transla-
tion. Used in conjunction with gateway_enable allows hosts
on private network addresses access to the Internet using
this host as a network address translating router.
ppp_profile
(str) The name of the profile to use from /etc/ppp/ppp.conf.
ppp_user (str) The name of the user under which ppp(8) should be
started. By default, ppp(8) is started as ``root''.
rc_conf_files
(str) This option is used to specify a list of files that
will override the settings in /etc/defaults/rc.conf. The
files will be read in the order in which they are specified
and should include the full path to the file. By default,
the files specified are /etc/rc.conf and /etc/rc.conf.local
gbde_autoattach_all
(bool) If set to ``YES'', /etc/rc.d/gbde will attempt to
automatically initialize your .bde devices in /etc/fstab.
gbde_devices
(str) List the devices that the script should try to attach,
or ``AUTO''.
gbde_lockdir
(str) The directory where the gbde(4) lockfiles are located.
The default lockfile directory is /etc.
The lockfile for each individual gbde(4) device can be over-
ridden by setting the variable gbde_lock_<device>, where
device is the encrypted device without the ``/dev/'' and
``.bde'' parts.
gbde_attach_attempts
(int) Number of times to attempt attaching to a gbde(4)
device, i.e., how many times the user is asked for the pass-
phrase. Default is 3.
geli_devices
(str) List of devices to automatically attach on boot. Note
that .eli devices from /etc/fstab are automatically appended
to this list.
geli_tries (int) Number of times user is asked for the pass-phrase. If
empty, it will be taken from kern.geom.eli.tries sysctl vari-
able.
geli_default_flags
(str) Default flags to use by geli(8) when configuring disk
encryption. Flags can be configured for every device sepa-
rately by defining geli_<device>_flags variable.
geli_autodetach
(str) Specifies if GELI devices should be marked for detach
on last close after file systems are mounted. Default is
``YES''. This can be changed for every device separately by
defining geli_<device>_autodetach variable.
geli_swap_flags
Options passed to the geli(8) utility when encrypted GEOM
providers for swap partitions are created. The default is
``-a aes -l 256 -s 4096 -d''.
root_rw_mount
(bool) Set to ``YES'' by default. After the file systems are
checked at boot time, the root file system is remounted as
read-write if this is set to ``YES''. Diskless systems that
mount their root file system from a read-only remote NFS
share should set this to ``NO'' in their rc.conf.
fsck_y_enable
(bool) If set to ``YES'', fsck(8) will be run with the -y
flag if the initial preen of the file systems fails.
background_fsck
(bool) If set to ``YES'', the system will attempt to run
fsck(8) in the background where possible.
background_fsck_delay
(int) The amount of time in seconds to sleep before starting
a background fsck(8). It defaults to sixty seconds to allow
large applications such as the X server to start before disk
I/O bandwidth is monopolized by fsck(8).
netfs_types
(str) List of file system types that are network-based. This
list should generally not be modified by end users. Use
extra_netfs_types instead.
extra_netfs_types
(str) If set to something other than ``NO'' (the default),
this variable extends the list of file system types for which
automatic mounting at startup by rc(8) should be delayed
until the network is initialized. It should contain a white-
space-separated list of network file system descriptor pairs,
each consisting of a file system type as passed to mount(8)
and a human-readable, one-word description, joined with a
colon (`:'). Extending the default list in this way is only
necessary when third party file system types are used.
syslogd_enable
(bool) If set to ``YES'', run the syslogd(8) daemon.
syslogd_program
(str) Path to syslogd(8) (default /usr/sbin/syslogd).

(bool) If set to ``YES'', run the inetd(8) daemon.
inetd_program
(str) Path to inetd(8) (default /usr/sbin/inetd).
inetd_flags
(str) If inetd_enable is set to ``YES'', these are the flags

to pass to named(8).
named_pidfile
(str) This is the default path to the named(8) daemon's PID
file. This must match the location in named.conf(5).
named_uid (str) The user that the named process should be run as.
named_chrootdir
(str) The root directory for a name server run in a chroot(8)
environment (default /var/named). If left empty named(8)
will not be run in a chroot(8) environment.
named_chroot_autoupdate
(bool) Set to ``NO'' to disable automatic update of the
chroot(8) environment.
named_symlink_enable
(bool) Set to ``NO'' to disable symlinking of daemon's PID
file into the chroot(8) environment.
kerberos5_server_enable
(bool) Set to ``YES'' to start a Kerberos 5 authentication
server at boot time.
