Diskless Cluster Computing: Security Benefit of oneSIS and Git

From desktops to servers to even the largest of supercomputers managing a constantly evolving diskless computing environment is usually quite challenging. Not only does the requirements for machines change over time but the need for timely security patching can make the maintenance unbearable. Creating a single diskless Linux image that is both easily customizable to different classes of machines, eg. clients versus servers, is easily solved with the use of oneSIS. Git, a version control system, provides a very easy method for upgrading, downgrading and verifying diskless images. The joining of these two software packages can easily save hundreds of hours for an administrator.
