Introduction to Configuring Key Linux Components


In this course you will learn how to configure key Linux components, and you will troubleshoot common and uncommon problems.

1.1. Setting the System Locale

System-wide locale settings are stored in the /etc/locale.conf file, which is read at early boot by the systemd daemon.The locale settings configured in /etc/locale.conf are inherited by every service or user, unless individual programs or individual users override them. The basic file format of /etc/locale.conf is a newline-separated list of variable assignments. For example, German locale with English messages in /etc/locale.conf looks as follows:
LANG =de_DE.UTF-8
LC_MESSAGES =C
Here, the LC_MESSAGES option determines the locale used for diagnostic messages written to the standard error output. To further specify locale settings in /etc/locale.conf, you can use several other options, most relevant are summarized in Table 1.1, “Options configurable in /etc/locale.conf” See the locale(7) manual page for detailed information on these options. Note that the LC_ALL option, which represents all possible options, should not be configured in /etc/locale.conf.
The changes in the desktop area for the next version of Red Hat Linux involve three major pieces:
  1. Develop a set of artwork in-house to use for the desktops as well as for other pieces of the distribution. This set of artwork, the Bluecurve look, includes, among other things, desktop backgrounds, widget themes, window border themes, and icons.
  2. We have configured the default settings and application shortcuts for both desktops in a similar fashion.
  3. In a few places where we feel that there are significant advantages to sharing underlying technology between the desktops, we have made code modifications to use this technology. An examples of this is modifying both desktops to use Xft2 and fontconfig for font rendering.
