Fedora/CentOS RPMs for Otto project, Packer and Vault

Do you always think twice before downloading software that comes in a tar or zip file? Me too, I like to manage my software in easy and straightforward manner and that’s why I repackaged Otto, Packer and Vault in RPM format. If you are running Fedora, CentOS or RHEL 6 you can now use my Copr repositories for the mentioned software from HashiCorp.

Writing a general multi-provider Vagrantfile

Vagrant is a great software that allows people to use various providers, provisioners, sync options, and more.

But lately I was writing a Vagrantfile for upcoming Fedora Developer Portal and wanted to support both Fedora users running our packages with libvirt as a default provider and everyone else as well.
