Linux From Scratch - Version 7.0

• The following example illustrates keymap autoconversion from ISO-8859-15 to UTF-8 and enabling dead keys

in Unicode mode:

cat > /etc/sysconfig/console << "EOF"

# Begin /etc/sysconfig/console

UNICODE="1"

KEYMAP="de-latin1"

KEYMAP_CORRECTIONS="euro2"

LEGACY_CHARSET="iso-8859-15"

FONT="LatArCyrHeb-16 -m 8859-15"

# End /etc/sysconfig/console

EOF

• Some keymaps have dead keys (i.e., keys that don't produce a character by themselves, but put an accent on

the character produced by the next key) or define composition rules (such as: “press Ctrl+. A E to get Æ” in

the default keymap). Linux-3.1 interprets dead keys and composition rules in the keymap correctly only when

the source characters to be composed together are not multibyte. This deficiency doesn't affect keymaps for

European languages, because there accents are added to unaccented ASCII characters, or two ASCII characters

are composed together. However, in UTF-8 mode it is a problem, e.g., for the Greek language, where one

sometimes needs to put an accent on the letter “alpha”. The solution is either to avoid the use of UTF-8, or to

install the X window system that doesn't have this limitation in its input handling.

• For Chinese, Japanese, Korean and some other languages, the Linux console cannot be configured to display

the needed characters. Users who need such languages should install the X Window System, fonts that cover the

necessary character ranges, and the proper input method (e.g., SCIM, it supports a wide variety of languages).

Note

The /etc/sysconfig/console file only controls the Linux text console localization. It has nothing to

do with setting the proper keyboard layout and terminal fonts in the X Window System, with ssh sessions or

with a serial console. In such situations, limitations mentioned in the last two list items above do not apply.

7.11. Configuring the sysklogd Script

The sysklogd script invokes the syslogd program with the -m 0 option. This option turns off the periodic

timestamp mark that syslogd writes to the log files every 20 minutes by default. If you want to turn on this periodic

timestamp mark, edit /etc/sysconfig/rc.site and define the variable SYSKLOGD_PARMS to the desired

value. For instance, to remove all parameters, set the variable to a null value:

SYSKLOGD_PARMS=

See man syslogd for more options.

7.12. The rc.site File

The optional /etc/sysconfig/rc.site file contains settings that are automatically set for each boot script. It

can alternatively set the values specified in the hostname, console, and clock files in the /etc/sysconfig/

directory. If the associated variables are present in both these separate files and rc.site, the values in the script

specific files have precedence.
