==========
Name
----
rc.conf - Arch Linux main configuration file
Synopsis
--------
*/etc/rc.conf*
Description
-----------
The */etc/rc.conf* file is the system configuration file for Arch-specific
settings. The format is bash. It contains several commonly-edited settings such
as timezone; keymap; kernel modules; daemons to load at start-up; etc. It's
split up in a few sections to categorize configuration settings: localization,
hardware, networking and daemons.
Localization[[L]]
-----------------
*TIMEZONE*::
Specifies your time zone. Possible time zones are the relative path to a zoneinfo file starting
from the directory /usr/share/zoneinfo. For example, a German timezone would be Europe/Berlin,
which refers to the file /usr/share/zoneinfo/Europe/Berlin.
Note: if unset, the value in /etc/localtime is used unchanged
Default: "Canada/Pacific"
*HARDWARECLOCK*::
How to interpret/update the hardware clock. (used by hwclock)
Options:
- empty: fall back to the value in /var/lib/hwclock/adjfile, which defaults to UTC. (recommended)
- "UTC": most robust, allows operating systems to abstract local time and ease DST.
- "localtime": apply timezone (and DST) in hardwareclock: discouraged.
Choose this if you dualboot with an OS which cannot handle UTC BIOS times correctly, like Windows.
- any other value will result in the hardware clock being left untouched (useful for virtualization)
Default: empty
*KEYMAP*::
Defines the keymap to load with the loadkeys program on bootup.
Possible keymaps are found in /usr/share/kbd/keymaps. Please note that this
setting is only valid for your TTYs, not any graphical window managers or X.
Defalut: empty
*CONSOLEFONT*::
Defines the console font to load with the setfont program on bootup.
Possible fonts are found in /usr/share/kbd/consolefonts. (only needed for non-US)
Default: empty
*CONSOLEMAP*::
Defines the console map to load with the setfont program on bootup.
Possible maps are found in /usr/share/kbd/consoletrans.
Set this to a map suitable for the appropriate locale (8859-1 for Latin1, for example)
if you're using an UTF-8 locale and use programs that generate 8-bit output.
If you're using X11 for everyday work, don't bother,
as it only affects the output of Linux console applications.
Default: empty
*LOCALE*::
This sets your system language, which will be used by all i18n-friendly applications and utilities.
See `locale -a` (or locale.gen) for available options. LANG in /etc/locale.conf takes precedence.
If unset, it falls back to the C locale.
Default: empty
*DAEMON_LOCALE*::
If set to 'yes', use $LOCALE as the locale during daemon startup and during the boot process.
If set to 'no', the C locale is used.
Default: "no"
*USECOLOR*::
use ANSI color sequences in startup messages
Default: "yes"
Hardware[[H]]
-------------
*MODULES*::
Modules to load at boot-up. To blacklist modules, see "man modprobe.conf".
Default: ().
*UDEV_TIMEOUT*::
Udev settle timeout.
Default: 30
*USEDMRAID*::
Scan for FakeRAID (dmraid) Volumes at startup.
Default: "no"
*USEBTRFS*::
Scan for BTRFS volumes at startup.
Default: "no"
*USELVM*::
Scan for LVM volume groups at startup, required if you use LVM.
Default: "no"
Networking[[N]]
---------------
*HOSTNAME*::
Hostname of machine. Should also be put in /etc/hosts.
Default: "myhost"
The following settings help you setting up a wired network.
*interface*::
Name of device.
Default: empty
Required for manual configuration as well as DHCP.
Use 'ip addr' or 'ls /sys/class/net/' to see all available interfaces.
*address*::
IP address.
Default: empty
Required for manual configuration, empty for DHCP.
*netmask*::
Subnet mask.
Default: empty (which means 255.255.255.0)
Optional for manual configuration, ignored for DHCP.
*broadcast*::
Broadcast address.
Default: empty
Optional for manual configuration, ignored for DHCP.
*gateway*::
Default route.
Default: empty
Required for manual configuration, ignored for DHCP.
*Static IP example*::
interface=eth0
address=192.168.0.2
netmask=255.255.255.0
broadcast=192.168.0.255
gateway=192.168.0.1
*DHCP example*::
interface=eth0
address=
netmask=
gateway=
The following options might be needed for advanced use-cases.
*NETWORK_PERSIST*::
Setting this to "yes" will skip network shutdown.
This is required if your root device is on NFS.
Default: "no"
*NETWORKS*::
Enable these netcfg profiles at boot-up. These are useful if you happen to
need more advanced network features than the simple network service
supports, such as multiple network configurations (ie, laptop users)
- set to 'menu' to present a menu during boot-up (dialog package required)
- prefix an entry with a ! to disable it
Network profiles are found in /etc/network.d
This requires the netcfg package
Default: (main), (commented out).
Daemons[[D]]
------------
*DAEMONS*::
Daemons to start at boot-up (in this order)
- prefix a daemon with a ! to disable it
- prefix a daemon with a @ to start it up in the background
If you are sure nothing else touches your hardware clock (such as ntpd or
a dual-boot), you might want to enable 'hwclock'. Note that this will only
make a difference if the hwclock program has been calibrated correctly.
If you use a network filesystem you should enable 'netfs'.
Default: (syslog-ng network crond)
