Chapter 3. GSettings and dconf
One of the major changes in Red Hat Enterprise Linux 7 is the transition from
GConf (for storing user preferences) to the combination of the
GSettings high-level configuration system and the
dconf back end.
- As mentioned above, the
GConfconfiguration system has been replaced by two systems:
dconfback end which serves as a low-level configuration system and program that collects system hardware and software configuration details in a single compact binary format.
gsettingscommand-line tool and the
dconfutility are used to view and change user settings. The
gsettingsutility does so directly in the terminal, while the
dconfutility uses the
dconf-editorGUI for editing a configuration database. See Chapter 9, Configuring Desktop with GSettings and dconf for more information on

- The concept of keyfiles has been introduced in Red Hat Enterprise Linux 7: the dconf utility allows the system administrator to override the default settings by directly installing defaults overrides. For example, setting the default background for all users is now executed by using a dconf override placed in a keyfile in the keyfile directory, such as
/etc/dconf/db/local.d/). To learn more about default values and overriding, see Section 9.5, “Configuring Custom Default Values”.
- Locking the Settings
dconfsystem now allows individual settings or entire settings subpaths to be locked down to prevent user customization. For more information on how to lock settings, see Section 9.5.1, “Locking Down Specific Settings”.
- NFS and dconf
- Using the
dconfutility on home directories shared over
NFSrequires additional configuration. See Section 9.7, “Storing User Settings Over NFS” for information on this topic.
