+.SH "NAME"
+systemd.mount \- Mount unit configuration
+.SH "SYNOPSIS"
+.PP
+\fImount\fR\&.mount
+.SH "DESCRIPTION"
+.PP
+A unit configuration file whose name ends in
+"\&.mount"
+encodes information about a file system mount point controlled and supervised by systemd\&.
+.PP
+This man page lists the configuration options specific to this unit type\&. See
+\fBsystemd.unit\fR(5)
+for the common options of all unit configuration files\&. The common configuration items are configured in the generic [Unit] and [Install] sections\&. The mount specific configuration options are configured in the [Mount] section\&.
+.PP
+Additional options are listed in
+\fBsystemd.exec\fR(5), which define the execution environment the
+\fBmount\fR(8)
+program is executed in, and in
+\fBsystemd.kill\fR(5), which define the way the processes are terminated, and in
+\fBsystemd.resource-control\fR(5), which configure resource control settings for the processes of the service\&.
+.PP
+Note that the options
+\fIUser=\fR
+and
+\fIGroup=\fR
+are not useful for mount units\&. systemd passes two parameters to
+\fBmount\fR(8); the values of
+\fIWhat=\fR
+and
+\fIWhere=\fR\&. When invoked in this way,
+\fBmount\fR(8)
+does not read any options from
+/etc/fstab, and must be run as UID 0\&.
+.PP
+Mount units must be named after the mount point directories they control\&. Example: the mount point
+/home/lennart
+must be configured in a unit file
+home\-lennart\&.mount\&. For details about the escaping logic used to convert a file system path to a unit name, see
+\fBsystemd.unit\fR(5)\&. Note that mount units cannot be templated, nor is possible to add multiple names to a mount unit by creating symlinks to its unit file\&.
+.PP
+Optionally, a mount unit may be accompanied by an automount unit, to allow on\-demand or parallelized mounting\&. See
+\fBsystemd.automount\fR(5)\&.
+.PP
+Mount points created at runtime (independently of unit files or
+/etc/fstab) will be monitored by systemd and appear like any other mount unit in systemd\&. See
+/proc/self/mountinfo
+description in
+\fBproc\fR(5)\&.
+.PP
+Some file systems have special semantics as API file systems for kernel\-to\-userspace and userspace\-to\-userspace interfaces\&. Some of them may not be changed via mount units, and cannot be disabled\&. For a longer discussion see
+\m[blue]\fBAPI File Systems\fR\m[]\&\s-2\u[1]\d\s+2\&.
+.PP
+The
+\fBsystemd-mount\fR(1)
+command allows creating
+\&.mount
+and
+\&.automount
+units dynamically and transiently from the command line\&.

+.RE
+.PP
+Mount units referring to local and network file systems are distinguished by their file system type specification\&. In some cases this is not sufficient (for example network block device based mounts, such as iSCSI), in which case
+\fB_netdev\fR
+may be added to the mount option string of the unit, which forces systemd to consider the mount unit a network mount\&.
+.SH "FSTAB"
+.PP
+Mount units may either be configured via unit files, or via
+/etc/fstab
+(see
+\fBfstab\fR(5)
+for details)\&. Mounts listed in
+/etc/fstab
+will be converted into native units dynamically at boot and when the configuration of the system manager is reloaded\&. In general, configuring mount points through
+/etc/fstab
+is the preferred approach to manage mounts for humans\&. For tooling, writing mount units should be preferred over editing
+/etc/fstab\&. See
+\fBsystemd-fstab-generator\fR(8)
+for details about the conversion from
+/etc/fstab
+to mount units\&.
+.PP
+The NFS mount option
+\fBbg\fR
+for NFS background mounts as documented in
+\fBnfs\fR(5)
+is detected by
+\fBsystemd\-fstab\-generator\fR
+and the options are transformed so that systemd fulfills the job\-control implications of that option\&. Specifically
+\fBsystemd\-fstab\-generator\fR
+acts as though
+"x\-systemd\&.mount\-timeout=infinity,retry=10000"
+was prepended to the option list, and
+"fg,nofail"
+was appended\&. Depending on specific requirements, it may be appropriate to provide some of these options explicitly, or to make use of the
+"x\-systemd\&.automount"
+option described below instead of using
+"bg"\&.
+.PP
+When reading
+/etc/fstab
+a few special mount options are understood by systemd which influence how dependencies are created for mount points\&. systemd will create a dependency of type
+\fIWants=\fR
+or
+\fBRequires=\fR
+(see option
+\fBnofail\fR
+below), from either
+local\-fs\&.target
+or
+remote\-fs\&.target, depending whether the file system is local or remote\&.

+.RS 4
+Configures a

+\fIAfter=\fR
+dependency between the created mount unit and another systemd unit, such as a device or mount unit\&. The argument should be a unit name, or an absolute path to a device node or mount point\&. This option may be specified more than once\&. This option is particularly useful for mount point declarations that need an additional device to be around (such as an external journal device for journal file systems) or an additional mount to be in place (such as an overlay file system that merges multiple mount points)\&. See
+\fIAfter=\fR

+.RE
+.PP
+\fB_netdev\fR
+.RS 4
+Normally the file system type is used to determine if a mount is a "network mount", i\&.e\&. if it should only be started after the network is available\&. Using this option overrides this detection and specifies that the mount requires network\&.

+With
+\fBnoauto\fR, the mount unit will not be added as a dependency for
+local\-fs\&.target

+\fBauto\fR

+\fBx\-systemd\&.automount\fR

+With
+\fBnofail\fR, this mount will be only wanted, not required, by
+local\-fs\&.target

+\fBx\-initrd\&.mount\fR
+.RS 4
+An additional filesystem to be mounted in the initrd\&. See
+initrd\-fs\&.target
+description in
+\fBsystemd.special\fR(7)\&. This is both an indicator to the initrd to mount this partition early and an indicator to the host to leave the partition mounted until final shutdown\&. Or in other words, if this flag is set it is assumed the mount shall be active during the entire regular runtime of the system, i\&.e\&. established before the initrd transitions into the host all the way until the host transitions to the final shutdown phase\&.
+.RE
+.PP
+If a mount point is configured in both
+/etc/fstab
+and a unit file that is stored below
+/usr/, the former will take precedence\&. If the unit file is stored below
+/etc/, it will take precedence\&. This means: native unit files take precedence over traditional configuration files, but this is superseded by the rule that configuration in
+/etc/
+will always take precedence over configuration in
+/usr/\&.
+.SH "OPTIONS"
+.PP
+Mount unit files may include [Unit] and [Install] sections, which are described in
+\fBsystemd.unit\fR(5)\&.
+.PP
+Mount unit files must include a [Mount] section, which carries information about the file system mount points it supervises\&. A number of options that may be used in this section are shared with other unit types\&. These options are documented in
+\fBsystemd.exec\fR(5)

+\fBsystemd.kill\fR(5)\&. The options specific to the [Mount] section of mount units are the following:
+.PP
+\fIWhat=\fR
+.RS 4
+Takes an absolute path of a device node, file or other resource to mount\&. See
+\fBmount\fR(8)
+for details\&. If this refers to a device node, a dependency on the respective device unit is automatically created\&. (See
+\fBsystemd.device\fR(5)
+for more information\&.) This option is mandatory\&. Note that the usual specifier expansion is applied to this setting, literal percent characters should hence be written as
+"%%"\&. If this mount is a bind mount and the specified path does not exist yet it is created as directory\&.
+.RE
+.PP
+\fIWhere=\fR
+.RS 4
+Takes an absolute path of a file or directory for the mount point; in particular, the destination cannot be a symbolic link\&. If the mount point does not exist at the time of mounting, it is created as either a directory or a file\&. The former is the usual case; the latter is done only if this mount is a bind mount and the source (\fIWhat=\fR) is not a directory\&. This string must be reflected in the unit filename\&.
