NAME

6       systemd.automount - Automount unit configuration
7

SYNOPSIS

9       automount.automount
10

DESCRIPTION

12       A unit configuration file whose name ends in ".automount" encodes
13       information about a file system automount point controlled and
14       supervised by systemd.
15
16       This man page lists the configuration options specific to this unit
17       type. See systemd.unit(5) for the common options of all unit
18       configuration files. The common configuration items are configured in
19       the generic [Unit] and [Install] sections. The automount specific
20       configuration options are configured in the [Automount] section.
21
22       Automount units must be named after the automount directories they
23       control. Example: the automount point /home/lennart must be configured
24       in a unit file home-lennart.automount. For details about the escaping
25       logic used to convert a file system path to a unit name see
26       systemd.unit(5). Note that automount units cannot be templated, nor is
27       it possible to add multiple names to an automount unit by creating
28       additional symlinks to its unit file.
29
30       For each automount unit file a matching mount unit file (see
31       systemd.mount(5) for details) must exist which is activated when the
32       automount path is accessed. Example: if an automount unit
33       home-lennart.automount is active and the user accesses /home/lennart
34       the mount unit home-lennart.mount will be activated.
35
36       Automount units may be used to implement on-demand mounting as well as
37       parallelized mounting of file systems.

AUTOMATIC DEPENDENCIES

40   Implicit Dependencies
41       The following dependencies are implicitly added:
42
43       ·   If an automount unit is beneath another mount unit in the file
44           system hierarchy, both a requirement and an ordering dependency
45           between both units are created automatically.
46
47       ·   An implicit Before= dependency is created between an automount unit
48           and the mount unit it activates.
49
50   Default Dependencies
51       The following dependencies are added unless DefaultDependencies=no is
52       set:
53
54       ·   Automount units acquire automatic Before= and Conflicts= on
55           umount.target in order to be stopped during shutdown.
56

FSTAB

58       Automount units may either be configured via unit files, or via
59       /etc/fstab (see fstab(5) for details).
60
61       For details how systemd parses /etc/fstab see systemd.mount(5).
62
63       If an automount point is configured in both /etc/fstab and a unit file,
64       the configuration in the latter takes precedence.
65

OPTIONS

67       Automount files must include an [Automount] section, which carries
68       information about the file system automount points it supervises. The
69       options specific to the [Automount] section of automount units are the
70       following:
71
72       Where=
73           Takes an absolute path of a directory of the automount point. If
74           the automount point does not exist at time that the automount point
75           is installed, it is created. This string must be reflected in the
76           unit filename. (See above.) This option is mandatory.
77
78       DirectoryMode=
79           Directories of automount points (and any parent directories) are
80           automatically created if needed. This option specifies the file
81           system access mode used when creating these directories. Takes an
82           access mode in octal notation. Defaults to 0755.
83
84       TimeoutIdleSec=
85           Configures an idle timeout. Once the mount has been idle for the
86           specified time, systemd will attempt to unmount. Takes a unit-less
87           value in seconds, or a time span value such as "5min 20s". Pass 0
88           to disable the timeout logic. The timeout is disabled by default.
