.SH "NAME" file-hierarchy - systemd file system hierarchy requirements

.SH "DESCRIPTION"

.PP Operating systems using the [**systemd**(1)](/man/os/systemd/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].

.PP Many of the paths described here can be queried with the [**systemd-path**(1)](/man/os/systemd/systemd-path.1) tool.
