file-hierarchy7

Overview

Operating systems using the systemd(1) system and service manager are organized based on a file system hierarchy inspired by UNIX, as described in UAPI.9 Linux File System Hierarchy[1]. Additional requirements on when given parts of the hierarchy must be available during boot are listed in Mount Requirements[2].

Many of the paths described here can be queried with the systemd-path(1) tool.
