.SH "NAME"
file-hierarchy \- systemd file system hierarchy requirements
.SH "DESCRIPTION"
.PP
Operating systems using the
\fBsystemd\fR(1)
system and service manager are organized based on a file system hierarchy inspired by UNIX, as described in
\m[blue]\fBUAPI\&.9 Linux File System Hierarchy\fR\m[]\&\s-2\u[1]\d\s+2\&. Additional requirements on
\fIwhen\fR
given parts of the hierarchy must be available during boot are listed in
\m[blue]\fBMount Requirements\fR\m[]\&\s-2\u[2]\d\s+2\&.
.PP
Many of the paths described here can be queried with the
\fBsystemd-path\fR(1)
tool\&.
