Technical requirements

This chapter will deal with disparate package managers and multiple ways of doing the same thing (which pretty much sums up Linux in general).

   ubuntu1804.vm.box_version = "20180927.0.0"
 end

end

Spinning up these boxes (with vagrant up) will provide you with a CentOS installation, a...
