We know that live patching has real benefits because it significantly reduces the downtime associated with frequent patching. But live patching is relatively difficult to achieve without causing other problems and for that reason live patching is not implemented as frequently as it could be. After all the last thing sysadmins want is a live patch that crashes a system.
Reproducible builds are one of the tools that can help developers to implement live patching consistently and safely. In this article I explain why reproducible builds matter for live patching what exactly reproducible builds are and how containers are coming to the rescue.
Patching is a critical part of systems maintenance because patching fixes faulty and buggy code. More importantly security teams rely on patching to plug security holes and there is a real urgency to it. Waiting for a convenient maintenance window to patch is risky because it leaves an opportunity for hackers to take advantage of an exploit.
