DNF

Used by Fedora guests, will get configured under guest's /var/cache/dnf. It will also make sure that keepcache is set to 1 on guest's /etc/dnf/dnf.conf.

To manually enable it:

Vagrant.configure("2") do |config|
  config.vm.box = 'some-fedora-box'
  config.cache.enable :dnf
end

⚠️ Notice about Windows hosts ⚠️

In case this bucket is enabled and a Windows host is in use, you might see an ugly stacktrace as described on this comment if some DNF repository is not available during provisioning.
