Explore a 34-minute conference talk from USENIX LISA14 that introduces PMR, an innovative tool leveraging procfs, systemd, and cgroups for minimum-impact daemon and library updates. Learn how modern Linux kernels, combined with systemd's use of cgroups, enable precise identification of services requiring restart or reload after file updates. Discover how PMR, a free and open-source tool, automates this process, allowing administrators to respond quickly to security vulnerabilities while minimizing downtime. Gain insights into balancing rapid update deployment with careful system management in this presentation by David Strauss from Pantheon.
