# Yum Used by CentOS guests, will get configured under guest's `/var/cache/yum`. It will also [make sure](lib/vagrant-cachier/bucket/yum.rb#L20) that `keepcache` is set to `1` on guest's `/etc/yum.conf`. To manually enable it: ```ruby Vagrant.configure("2") do |config| config.vm.box = 'some-centos-box' config.cache.enable :yum 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 Yum repository is not available during provisioning.
