CentOS Stream at Facebook
summary
Facebook runs millions of physical servers and uses CentOS Stream 8 as the production base, with 85.5% of fleet migrated to Stream today. Tooling includes dcrpm for rpmdb corruption remediation, an NDB rpmdb (replacing berkeleydb), a Facebook backport layer on GitHub, and dual kernels (stable + near-mainline) for feature testing. Defaults are btrfs root + cgroup2, systemd psi/oomd in production, and DNF copy-on-write optimizations already deployed.
