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.
- GConf
- As mentioned above, the
GConf
configuration system has been replaced by two systems:- the
GSettings
API, and - the
dconf
back 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.
Both thegsettings
command-line tool and thedconf
utility are used to view and change user settings. Thegsettings
utility does so directly in the terminal, while thedconf
utility uses thedconf-editor
GUI for editing a configuration database. See Chapter 9, Configuring Desktop with GSettings and dconf for more information ondconf-editor
and thegsettings
utility. - gconftool
- The
gconftool-2
tool has been replaced bygsettings
anddconf
. Likewise,gconf-editor
has been replaced bydconf-editor
. - Overriding
- 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
- The
dconf
system 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
dconf
utility on home directories shared overNFS
requires additional configuration. See Section 9.7, “Storing User Settings Over NFS” for information on this topic.
