An overview of systemd's Dynamic Users feature, which creates ephemeral, runtime-only user accounts for service units without adding them to /etc/passwd. The article explains how this simplifies service packaging by eliminating the need to manually create or remove system users, and highlights the use of State Directories for persistent data storage.
Background
systemd is the dominant init system on modern Linux distributions, and Dynamic Users is one of its security-oriented features designed to reduce the attack surface of services by running them under ephemeral accounts.
