+# DNF

+Used by Fedora guests, will get configured under guest's `/var/cache/dnf`. It will
+also [make sure](lib/vagrant-cachier/bucket/dnf.rb#L20) that `keepcache` is set to
+`1` on guest's `/etc/dnf/dnf.conf`.
+
+To manually enable it:
+
+```ruby
+Vagrant.configure("2") do |config|
+  config.vm.box = 'some-fedora-box'
+  config.cache.enable :dnf
+end
+```
+
+### :warning: Notice about Windows hosts :warning:
+
+In case this bucket is enabled and a Windows host is in use, you might see an
+ugly stacktrace as described on [this comment](https://github.com/fgrehm/vagrant-cachier/issues/117#issuecomment-50548393)
+if some DNF repository is not available during provisioning.
