RC.CONF(5)

NAME
rc.conf - system startup configuration file

DESCRIPTION
The rc.conf file specifies which services are enabled during system startup by the startup scripts invoked by /etc/rc (see rc(8)), and the shutdown scripts invoked by /etc/rc.shutdown. The rc.conf file is a shell script that is sourced by rc(8), meaning that rc.conf must contain valid shell commands.

Listed below are the standard rc.conf variables that may be set, the values to which each may be set, a brief description of what each variable does, and a reference to relevant manual pages. Third party packages may test for additional variables.

By default, rc.conf reads /etc/defaults/rc.conf (if it is readable) to obtain default values for various variables, and the end-user may override these by appending appropriate entries to the end of rc.conf.

rc.d(8) scripts that use load_rc_config from rc.subr(8) also support sourcing an optional end-user provided per-script override file /etc/rc.conf.d/service, (where service is the contents of the name variable in the rc.d(8) script). This may contain variable overrides, including allowing the end-user to override various run_rc_command rc.d(8) control variables, and thus changing the operation of the script without requiring editing of the script.

  Variable naming conventions and data types
Most variables are one of two types: enabling variables or flags variables. Enabling variables, such as inetd, are generally named after the program or the system they enable, and have boolean values (specified using ‘YES’, ‘TRUE’, ‘ON’ or ‘1’ for true, and ‘NO’, ‘FALSE’, ‘OFF’ or ‘0’ for false, with the values being case insensitive). Flags variables, such as inetd_flags have the same name with “_flags” appended, and determine what arguments are passed to the program if it is enabled.

If a variable that rc(8) expects to be set is not set, or the value is not one of the allowed values, a warning will be printed.

  Overall control

do_rcshutdown
    Boolean value. If false, shutdown(8) will not run /etc/rc.shutdown.

rcshutdown_rcorder_flags
    A string. Extra arguments to the rcorder(8) run by /etc/rc.shutdown.

rcshutdown_timeout
    A number. If non-blank, use this as the number of seconds to run a watchdog timer for which will terminate /etc/rc.shutdown if the timer expires before the shutdown script completes.

rc_configured
    Boolean value. If false then the system will drop into single-user mode during boot.

rc_fast_and_loose
    If set to a non-empty string, each script in /etc/rc.d will be executed in the current shell rather than a sub shell. This may be faster on slow machines that have an expensive fork(2) operation.

    Note:
        Use this at your own risk! A rogue command or script may inadvertently prevent boot to multiuser.

rc_rcorder_flags
    A string. Extra arguments to the rcorder(8) run by /etc/rc.

rc_directories
    A string. Space separated list of directories searched for rc scripts. The default is /etc/rc.d. All directories in rc_directories must be located in the root file system, otherwise they will be silently skipped.

rc_silent
    Boolean value. If true then the usual output is suppressed, and rc(8) invokes the command specified in the rc_silent_cmd variable once for each line of suppressed output. The default value of rc_silent is set from the AB_SILENT flag in the kernel's boothowto variable (see boot(8), reboot(2)).

rc_silent_cmd
    A command to be executed once per line of suppressed output, when rc_silent is true. The default value of rc_silent_cmd is ‘twiddle’, which will display a spinning symbol instead of each line of output. Another useful value is ‘’:, which will display nothing at all.

  Basic network configuration

defaultroute
    A string. Default IPv4 network route. If empty or not set, then the contents of /etc/mygate (if it exists) are used.

defaultroute6
    A string. Default IPv6 network route. If empty or not set, then the contents of /etc/mygate6 (if it exists) are used.

domainname
    A string. NIS (YP) domain of host. If empty or not set, then the contents of /etc/defaultdomain (if it exists) are used.

force_down_interfaces
    A space separated list of interface names. These interfaces will be configured down when going from multiuser to single-user mode or on system shutdown.

dns_domain
    A string. Sets domain in /etc/resolv.conf.

dns_search
    A string. Sets search in /etc/resolv.conf.

dns_nameservers
    A string of space separated domain name servers. Sets nameserver for each value in /etc/resolv.conf.

dns_sortlist
    A string. Sets sortlist in /etc/resolv.conf.

dns_options
    A string. Sets options in /etc/resolv.conf.

dns_metric
    An unsigned integer. Sets the priority of the above DNS to other sources, lowest wins. Defaults to 0.

    This is important for some stateful interfaces, for example PPPoE interfaces which have no direct means of noticing “disconnect” events.

    All active pppoe(4) interfaces will be automatically added to this list.

hostname
    A string. Name of host. If empty or not set, then the contents of /etc/myname (if it exists) are used.

  Boottime file-system and swap configuration

critical_filesystems_local
    A string. File systems mounted very early in the system boot before networking services are available. Usually /var is part of this, because it is needed by services such as dhcpcd(8) which may be required to get the network operational. The default is ‘OPTIONAL:/var’, where the ‘OPTIONAL:’ prefix means that it's not an error if the file system is not present in fstab(5).

critical_filesystems_remote
    A string. File systems such as /usr that may require network services to be available to mount, that must be available early in the system boot for general services to use. The default is ‘OPTIONAL:/usr’, where the ‘OPTIONAL:’ prefix means that it is not an error if the file system is not present in fstab(5).

critical_filesystems_zfs
    A string. Mount non-legacy ZFS file systems right after mounting local file systems listed in critical_filesystems_local variable. An entry can be prefixed with ‘OPTIONAL:’ which means that it is not an error if the file system is not present among available ZFS datasets. The default is ''.

fsck_flags
    A string. A file system is checked with fsck(8) during boot before mounting it. This option may be used to override the default command-line options passed to the fsck(8) program.

    When set to -y, fsck(8) assumes yes as the answer to all operator questions during file system checks. This might be important with hosts where the administrator does not have access to the console and an unsuccessful shutdown must not make the host unbootable even if the file system checks would fail in preen mode.

modules
    Boolean value. If true, loads the modules specified in modules.conf(5).

no_swap
    Boolean value. Should be true if you have deliberately configured your system with no swap. If false and no swap devices are configured, the system will warn you.

resize_root
    Boolean value. Set to true to have the system resize the root file system to fill its partition. Will only attempt to resize the root file system if it is of type ffs and does not have logging enabled. Defaults to false.

swapoff
    Boolean value. Remove block-type swap devices at shutdown time. Useful if swapping onto RAIDframe devices.

swapoff_umount
    “auto” or “manual”. Before removing block-type swap devices, it is wise to unmount tmpfs filesystems to avoid having to swap their contents back into RAM. By default “(auto”) all tmpfs filesystems that contain no device nodes are unmounted. Set to “manual” to explicitly specify which filesystems to unmount before removing swap.

swapoff_umount_fs
    A space-separated list of absolute paths to tmpfs mount points. If swapoff_umount is set to “manual”, these tmpfs filesystems will be forcibly unmounted before removing block-type swap devices.

var_shm_symlink
    A path. If set, names a path that /var/shm will be symlinked to.

    The path needs to live on a tmpfs file system. A typical value (assuming /tmp is mounted on tmpfs) would be /tmp/.shm.

  Block device subsystems

ccd Boolean value. Configures concatenated disk devices according to ccd.conf(5).

cgd Boolean value. Configures cryptographic disk devices. Requires /etc/cgd/cgd.conf. See cgdconfig(8) for additional details.

lvm Boolean value. Configures the logical volume manager. See lvm(8) for additional details.

raidframe
    Boolean value. Configures raid(4), RAIDframe disk devices. See raidctl(8) for additional details.

zfs Boolean value. Configures ZFS storage pools and ZFS file systems.

  One-time actions to perform or programs to run on boot-up

accounting
    Boolean value. Enables process accounting with accton(8). Requires /var/account/acct to exist.

clear_tmp
    Boolean value. Clear /tmp after reboot.

dmesg
    Boolean value. Create /var/run/dmesg.boot from the output of dmesg(8). Passes dmesg_flags.

entropy
    A string, either ‘check’, ‘wait’, or ‘’ (empty). If set and nonempty, then during boot-up, after random_seed and rndctl, check for or wait until enough entropy before any networking is enabled.

    If not enough entropy is available, then:
    •   With ‘entropy=check’, stop multiuser boot and enter single-user mode instead.
    •   With ‘entropy=wait’, wait until enough entropy is available.

    Note that ‘entropy=wait’ may cause the system to hang indefinitely at boot if it has neither a random seed nor any hardware random number generators — use with care.

    If empty or not set, the system may come to multiuser without entropy, which is unsafe to use on the internet; it is the operator's responsibility to heed warnings from the kernel and the daily security.conf(5) report to remedy the problem — see entropy(7).

envsys
    Boolean value. Sets preferences for the environmental systems framework, envsys(4). Requires /etc/envsys.conf, which is described in envsys.conf(5).

gpio
    Boolean value. Configure gpio(4) devices. See gpio.conf(5).

ldconfig
    Boolean value. Configures a.out(5) runtime link editor directory cache.

mixerctl
    Boolean value. Read mixerctl.conf(5) for how to set mixer values. List in mixerctl_mixers the devices whose settings are to be saved at shutdown and restored at start-up.

newsyslog
    Boolean value. Run newsyslog to trim log files before syslogd starts. Intended for laptop users. Passes newsyslog_flags.

per_user_tmp
    Boolean value. Enables a per-user /tmp directory. per_user_tmp_dir can be used to override the default location of the “real” temporary directories, /private/tmp. See security(7) for additional details.

quota
    Boolean value. Checks and enables quotas by running quotacheck(8) and quotaon(8).

random_seed
    Boolean value. During boot-up, runs the rndctl(8) utility with the -L flag to seed the random number subsystem from an entropy file. During shutdown, runs the rndctl(8) utility with the -S flag to save some random information to the entropy file. The entropy file name is specified by the random_file variable, and defaults to /var/db/entropy-file. The entropy file must be on a local file system that is writable early during boot-up (just after the file systems specified in critical_filesystems_local have been mounted), and correspondingly late during shutdown.

rndctl
    Boolean value. Runs the rndctl(8) utility one or more times according to the specification in rndctl_flags.

    If rndctl_flags does not contain a semicolon (‘’); then it is expected to contain zero or more flags, followed by one or more device or type names. The rndctl(8) command will be executed once for each device or type name. If the specified flags do not include any of -c, -C, -e, or -E, then the flags -c and -e are added, to specify that entropy from the relevant device or type should be both collected and estimated. If the specified flags do not include either of -d or -t, then the flag -d is added, to specify that the non-flag arguments are device names, not type names.

    rndctl_flags may contain multiple semicolon-separated segments, in which each segment contains flags and device or type names as described above. This allows different flags to be associated with different device or type names. For example, given rndctl_flags="wd0 wd1; -t tty; -c -t net", the following commands will be executed: rndctl -c -e -d wd0; rndctl -c -e -d wd1; rndctl -c -e -t tty; rndctl -c -t net.

rtclocaltime
    Boolean value. Sets the real time clock to local time by adjusting the sysctl(7) value of kern.rtc_offset. The offset from UTC is calculated automatically according to the time zone information in the file /etc/localtime.

savecore
    Boolean value. Runs the savecore(8) utility. Passes savecore_flags. The directory where crash dumps are stored is specified by savecore_dir. The default setting is /var/crash.

sysdb
    Boolean value. Builds various system databases, including /var/run/dev.cdb, /etc/spwd.db, /var/db/netgroup.db, /var/db/services.cdb, and entries for utmp(5).

tpctl
    Boolean value. Run tpctl(8) to calibrate touch panel device. Passes tpctl_flags.

update_motd
    Boolean value. Updates the NetBSD version string in the /etc/motd file to reflect the version of the running kernel. See motd(5).

update_motd_release
    Boolean value. If enabled in addition to update_motd, updates a second NetBSD version string in the /etc/motd file to reflect the version, architecture, and Build ID of the installed userland. An optional prefix can be provided for this version string in motd_release_tag.

virecover
    Boolean value. Send notification mail to users if any recoverable files exist in /var/tmp/vi.recover. Read virecover(8) for more information.

wdogctl
    Boolean value. Configures watchdog timers. Passes wdogctl_flags. Refer to wdogctl(8) for information on how to configure a timer.

  System security settings

securelevel
    A number. The system securelevel is set to the specified value early in the boot process, before any external logins, or other programs that run users job, are started. If set to nothing, the default action is taken, as described in init(8) and secmodel_securelevel(9), which contains definitive information about the system securelevel. Note that setting securelevel to 0 in rc.conf will actually result in the system booting with securelevel set to 1, as init(8) will raise the level when rc(8) completes.

permit_nonalpha
    Boolean value. Allow passwords to include non-alpha characters, usually to allow NIS/YP netgroups.

veriexec
    Boolean value. Load Veriexec fingerprints during startup. Read veriexecctl(8) for more information.

veriexec_strict
    A number. Controls the strict level of Veriexec. Level 0 is learning mode, used when building the signatures file. It will only output messages but will not enforce anything. Level 1 will only prevent access to files with a fingerprint mismatch. Level 2 will also deny writing to and removing of monitored files, as well as enforce access type (as specified in the signatures file). Level 3 will take a step further and prevent access to files that are not monitored.

veriexec_verbose
    A number. Controls the verbosity of Veriexec. Recommended operation is at level 0, verbose output (mostly used when building the signatures file) is at level 1. Level 2 is for debugging only and should not be used.

veriexec_flags
    A string. Flags to pass to the veriexecctl command.

smtoff
    Boolean value. Disables SMT (Simultaneous Multi-Threading).

  Networking startup

altqd
    Boolean value. ALTQ configuration/monitoring daemon. Passes altqd_flags.

auto_ifconfig

blocklistd
    Boolean value. Runs blocklistd(8) to dynamically block hosts on a DoS according to configuration set in blocklistd.conf(5) Passes blocklistd_flags.

dhcpcd
    Boolean value. Set true to configure some or all network interfaces using dhcpcd. If you set dhcpcd true, then /var must be in critical_filesystems_local, or /var must be on the root file system. If you need to restrict dhcpcd to one or a number of interfaces, or need a separate configuration per interface, then this should be done in the configuration file - see dhcpcd.conf(5) for details.

dhcpcd_flags
    Passes dhcpcd_flags to dhcpcd. See dhcpcd(8) for complete documentation.

flushroutes
    Boolean value. Flushes the route table on networking startup. Useful when coming up to multiuser mode after going down to single-user mode.

ftp_proxy
    Boolean value. Runs ftp-proxy(8), the proxy daemon for the Internet File Transfer Protocol.

hostapd
    Boolean value. Runs hostapd(8), the authenticator for IEEE 802.11 networks.

ifaliases_*
    A string. List of ‘address netmask’ pairs to configure additional network addresses for the given configured interface (e.g. ifaliases_le0). If netmask is ‘-’, then use the default netmask for the interface.

    ifaliases_* covers limited cases only and is considered unrecommended. We recommend using ifconfig_xxN variables or /etc/ifconfig.xxN files with multiple lines instead.

ifwatchd
    Boolean value. Monitor dynamic interfaces and perform actions upon address changes. Passes ifwatchd_flags.

ip6addrctl
    Boolean value. Fine grain control of address and routing priorities.

ip6addrctl_policy
    A string. Can be:
    ‘auto’
        automatically determine from system settings; will read priorities from /etc/ip6addrctl.conf or if that file does not exist it will default to IPv6 first, then IPv4.
    ‘ipv4_prefer’
        try IPv4 before IPv6.
    ‘ipv6_prefer’
        try IPv6 before IPv4.

ip6addrctl_verbose
    Boolean value. If set, print the resulting prefixes and priorities map.

ip6mode
    A string. An IPv6 node can be a router (nodes that forward packet for others) or a host (nodes that do not forward). A host can be autoconfigured based on the information advertised by adjacent IPv6 routers. By setting ip6mode to ‘router’, ‘host’, or ‘autohost’, you can configure your node as a router, a non-autoconfigured host, or an autoconfigured host. Invalid values will be ignored, and the node will be configured as a non-autoconfigured host.

ip6uniquelocal
    Boolean value. If ip6mode is equal to ‘router’, and ip6uniquelocal is false, a reject route will be installed on boot to avoid misconfiguration relating to unique-local addresses. If ip6uniquelocal is true, the reject route won't be installed.

ipfilter
    Boolean value. Runs ipf(8) to load in packet filter specifications from /etc/ipf.conf at network boot time, before any interfaces are configured. Passes ipfilter_flags. See ipf.conf(5).

    Boolean value. Runs ipfs(8) to save and restore information for ipnat and ipfilter state tables. The information is stored in /var/db/ipf/ipstate.ipf and /var/db/ipf/ipnat.ipf. Passes ipfs_flags.

ipmon
    Boolean value. Runs ipmon(8) to read ipf(8) packet log information and log it to a file or the system log. Passes ipmon_flags.

ipmon_flags
    A string. Specifies arguments to supply to ipmon(8). Defaults to ‘-ns’. A typical example would be ‘-nD /var/log/ipflog’ to have ipmon(8) log directly to a file bypassing syslogd(8). If the -D argument is used, remember to modify /etc/newsyslog.conf accordingly; for example:

        /var/log/ipflog 640 10 100 * Z /var/run/ipmon.pid

ipnat
    Boolean value. Runs ipnat(8) to load in the IP network address translation (NAT) rules from /etc/ipnat.conf at network boot time, before any interfaces are configured. See ipnat.conf(5).

ipsec
    Boolean value. Runs setkey(8) to load in IPsec manual keys and policies from /etc/ipsec.conf at network boot time, before any interfaces are configured.

npf Boolean value. Loads npf.conf(5) at network boot time, and starts npf(7).

npfd
    Boolean value. Runs npfd(8), the NPF packet filter logging and state synchronization daemon. Passes npfd_flags.

net_interfaces
    A string. The list of network interfaces to be configured at boot time. For each interface "xxN", the system first looks for ifconfig parameters in the variable ifconfig_xxN, and then in the file /etc/ifconfig.xxN. If auto_ifconfig is false, and neither the variable nor the file is found, a warning is printed. Information in either the variable or the file is parsed identically, except that, if an ifconfig_xxN variable contains a single line with embedded semicolons, then the value is split into multiple lines prior to further parsing, treating the semicolon as a line separator.

    One common case it to set the ifconfig_xxN variable to a set of arguments to be passed to an ifconfig(8) command after the interface name. Refer to ifconfig.if(5) for more details on /etc/ifconfig.xxN files, and note that the information there also applies to ifconfig_xxN variables (after the variables are split into lines).

ntpdate
    Boolean value. Runs ntpdate(8) to set the system time from one of the hosts in ntpdate_hosts. If ntpdate_hosts is empty, it will attempt to find a list of hosts in /etc/ntp.conf. Passes ntpdate_flags.

pf  Boolean value. Enable pf(4) at network boot time: Load the initial configuration pf.boot.conf(5) before the network is up. After the network has been configured, then load the final rule set pf.conf(5).

pf_rules
    A string. The path of the pf.conf(5) rule set that will be used when loading the final rule set.

pflogd
    Boolean value. Run pflogd(8) for dumping packet filter logging information to a file.

ppp A boolean. Toggles starting pppd(8) on startup. See ppp_peers below.

ppp_peers
    A string. If ppp is true and ppp_peers is not empty, then /etc/rc.d/ppp will check each word in ppp_peers for a corresponding ppp configuration file in /etc/ppp/peers and will call pppd(8) with the “call peer” option.

racoon
    Boolean value. Runs racoon(8), the IKE (ISAKMP/Oakley) key management daemon.

wpa_supplicant
    Boolean value. Run wpa_supplicant(8), WPA/802.11i Supplicant for wireless network devices. If you set wpa_supplicant true, then /usr must be in critical_filesystems_local, or /usr must be on the root file system. dhcpcd ignores this variable, see the dhcpcd variable for details.

  Daemons required by other daemons

inetd
    Boolean value. Runs the inetd(8) daemon to start network server processes (as listed in /etc/inetd.conf) as necessary. Passes inetd_flags. The -l flag turns on libwrap connection logging.

rtadvd
    Boolean value. Runs rtadvd(8), the IPv6 router advertisement daemon, which is used to advertise information about the subnet to IPv6 end hosts. Passes rtadvd_flags. This is only for IPv6 routers, so set ip6mode to ‘router’ if you use it.

  X Window System daemons

xdm Boolean value. Runs the xdm(1) X display manager. These X daemons are available only with the optional X distribution of NetBSD.

xfs Boolean value. Runs the xfs(1) X11 font server, which supplies local X font files to X terminals.
