Background

I frequently check out Dustin Kirkland’s blog to get ideas about how to secure instances running on various cloud infrastructures.  Recently, I stumbled across one of his blog entries, where he discussed a package called ‘overlayroot‘, which is part of the cloud-initramfs-tools package for Ubuntu.  The really interesting feature I liked about this package is the ability to encrypt –…
