Configuring the Global DNF Configuration Settings
Edit the main configuration in /etc/dnf/dnf.conf. The global definitions for DNF are located under the [main] section heading of the DNF configuration file. The following table lists important directive for DNF.
Note:
For backward-compatibility purposes, a symbolic link to /etc/dnf/dnf.conf
is created at /etc/yum.conf. The configuration syntax is the same;
although, some configuration options have been deprecated and some new configuration options
have been added. See Comparing Yum Version 3 With DNF for a list of the differences between configuration options
and syntax.
See the dnf.conf(5) manual page for more information.
