+Subject: [PATCH] Fix: Python dnf API does not respect cacheonly
+ (RhBug:1862970)
+
+`Repo` object has always been constructed with default synchronization
+strategy. The configuration option `cacheonly` was ignored. DNF
+application set synchronization strategy later in the `Cli` object
+during processing demands.
+
+The fix takes into account the `cacheonly` option during the construction
+of the `Repo` object. Synchronization strategy may still be overriden
+during demand processing.
+
+Conflict: NA
+Reference: https://github.com/rpm-software-management/dnf/commit/118bd0c124377dad1a01e7bbd3ec58fb6700714c
