This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.

<title>Description</title>
|
|
|
|
<para>A unit configuration file whose name ends in
|
|
<literal>.automount</literal> encodes information about a file
|
|
system automount point controlled and supervised by
|
|
systemd.</para>
|
|
|
|
<para>This man page lists the configuration options specific to
|
|
this unit type. See
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
for the common options of all unit configuration files. The common
|
|
configuration items are configured in the generic [Unit] and
|
|
[Install] sections. The automount specific configuration options
|
|
are configured in the [Automount] section.</para>
|
|
|
|
<para>Automount units must be named after the automount
|
|
directories they control. Example: the automount point
|
|
<filename noindex='true'>/home/lennart</filename> must be
|
|
configured in a unit file
|
|
<filename>home-lennart.automount</filename>. For details about the
|
|
escaping logic used to convert a file system path to a unit name
|
|
see
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
|
|
|
|
<para>For each automount unit file a matching mount unit file (see
|
|
<citerefentry><refentrytitle>systemd.mount</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
for details) must exist which is activated when the automount path
|
|
is accessed. Example: if an automount unit
|
|
<filename>home-lennart.automount</filename> is active and the user
|
|
accesses <filename>/home/lennart</filename> the mount unit
|
|
<filename>home-lennart.mount</filename> will be activated.</para>
|
|
|
|
<para>Automount units may be used to implement on-demand mounting
|
|
as well as parallelized mounting of file systems.</para>
|
|
|
|
<para>If an automount point is beneath another mount point in the
|
|
file system hierarchy, a dependency between both units is created
|
|
automatically.</para>

<para>Automount units may either be configured via unit files, or

<para>If an automount point is configured in both

<filename>/etc/fstab</filename> and a unit file, the configuration

in the latter takes precedence.</para>

<para>Automount files must include an [Automount] section, which
|
|
carries information about the file system automount points it
|
|
supervises. The options specific to the [Automount] section of
|
|
automount units are the following:</para>
|
|
|
|
<variablelist class='unit-directives'>
|
|
|

<varlistentry>
|
|
<term><varname>Where=</varname></term>
|
|
<listitem><para>Takes an absolute path of a directory of the
|
|
automount point. If the automount point does not exist at time
|
|
that the automount point is installed, it is created. This
|
|
string must be reflected in the unit filename. (See above.)
|
|
This option is mandatory.</para></listitem>

<listitem><para>Directories of automount points (and any

parent directories) are automatically created if needed. This

option specifies the file system access mode used when

|
notation. Defaults to 0755.</para></listitem>

<listitem><para>Configures an idleness timeout. Once the mount has been

idle for the specified time, systemd will attempt to unmount. Takes a

Pass 0 to disable the timeout logic. The timeout is disabled by
