NAME

       systemd.mount - systemd mount configuration files

SYNOPSIS

       systemd.mount

DESCRIPTION

       A unit configuration file whose name ends in .mount encodes information about a file system mount point controlled and supervised by
       systemd.

       This man page lists the configuration options specific to this unit type. See systemd.unit(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.

       Additional options are listed in systemd.exec(5), which define the execution environment the mount(8) binary is executed in.

       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 systemd.unit(5).

       Optionally, a mount unit may be accompanied by an automount unit, to allow on-demand or parallelized mounting. See systemd.automount(5).

       If an mount point is beneath another mount point in the file system hierarchy, a dependency between both units is created automatically.

       Mount points created at runtime independent on unit files or /etc/fstab will be monitored by systemd and appear like any other mount unit
       in systemd.

/ETC/FSTAB
       Mount units may either be configured via unit files, or via /etc/fstab (see fstab(5) for details).

       When reading /etc/fstab a few special mount options are understood by systemd which influence how dependencies are created for mount points
       from /etc/fstab. If MountAuto=yes is set in system.conf (which is the default), or if comment=systemd.mount is specified as mount option,
       then systemd will create a dependency of type Wants from either local-fs.target or remote-fs.target, depending whether the file system is
       local or remote. If comment=systemd.automount is set, an automount unit will be created for the file system. See systemd.automount(5) for
       details. If x-systemd-device-timeout= is specified it may be used to configure how long systemd should wait for a device to show up before
       giving up on an entry from /etc/fstab. Specify a time in seconds or explicitly specifiy a unit as s, min, h, ms.

       If a mount point is configured in both /etc/fstab and a unit file, the configuration in the latter takes precedence.

OPTIONS

       Mount 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 systemd.exec(5). The options specific to
       the [Mount] section of mount units are the following:

       What=
	   Takes an absolute path of a device node, file or other resource to mount. See mount(8) for details. If this refers to a device node, a
	   dependency on the respective device unit is automatically created. (See systemd.device(5) for more information.) This option is
	   mandatory.

       Where=
	   Takes an absolute path of a directory of the mount point. If the mount point is not existing at time of mounting, it is created. This
	   string must be reflected in the unit file name. (See above.) This option is mandatory.

       Type=
	   Takes a string for the filesystem type. See mount(8) for details. This setting is optional.

       Options=
	   Mount options to use when mounting. This takes a comma separated list of options. This setting is optional.

       DirectoryMode=
	   Directories of mount points (and any parent directories) are automatically created if needed. This option specifies the file system
	   access mode used when creating these directories. Takes an access mode in octal notation. Defaults to 0755.

       TimeoutSec=
	   Configures the time to wait for the mount command to finish. If a command does not exit within the configured time the mount will be
	   considered failed and be shut down again. All commands still running will be terminated forcibly via SIGTERM, and after another delay
	   of this time with SIGKILL. (See KillMode= below.) Takes a unit-less value in seconds, or a time span value such as "5min 20s". Pass 0
	   to disable the timeout logic. Defaults to 90s.

       KillMode=
	   Specifies how processes of this mount shall be killed. One of control-group, process, none.

	   This option is mostly equivalent to the KillMode= option of service files. See systemd.service(5) for details.

       KillSignal=
	   Specifies which signal to use when killing a process of this mount. Defaults to SIGTERM.

       SendSIGKILL=
	   Specifies whether to send SIGKILL to remaining processes after a timeout, if the normal shutdown procedure left processes of the mount
	   around. Takes a boolean value. Defaults to "yes".
