Filipe Brandenburger 681eb9cf2b man: generate configured paths in manpages
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions
like Debian which still have not adopted a /usr merge setup.

Use XML entities from man/custom-entities.ent to replace configured paths while
doing XSLT processing of the original XML files. There was precedent of some
files (such as systemd.generator.xml) which were already using this approach.

This addresses most of the (manual) fixes from this patch:
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220

The idea of using generic XML entities was presented here:
http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html

This patch solves almost all the issues, with the exception of:
- Path to /bin/mount and /bin/umount.
- Generic statements about preference of /lib over /etc.

These will be handled separately by follow up patches.

Tested:
- With default configure settings, ran "make install" to two separate
  directories and compared the output to confirm they matched exactly.
- Used a set of configure flags including $CONFFLAGS from Debian:
  http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules
  Installed the tree and confirmed the paths use /lib/systemd instead of
  /usr/lib/systemd and that no other unexpected differences exist.
- Confirmed that `make distcheck` still passes.

<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>
</refsect1>
<refsect1>
<title><filename>fstab</filename></title>
<para>Automount units may either be configured via unit files, or
via <filename>/etc/fstab</filename> (see
<citerefentry project='man-pages'><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for details).</para>
<para>For details how systemd parses
<filename>/etc/fstab</filename> see
<citerefentry><refentrytitle>systemd.mount</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
<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>
</refsect1>
<refsect1>
<title>Options</title>
<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>
</varlistentry>
<varlistentry>
<term><varname>DirectoryMode=</varname></term>
<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
creating these directories. Takes an access mode in octal
notation. Defaults to 0755.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>TimeoutIdleSec=</varname></term>
<listitem><para>Configures an idleness timeout. Once the mount has been
idle for the specified time, systemd will attempt to unmount. Takes a
unit-less value in seconds, or a time span value such as "5min 20s".
Pass 0 to disable the timeout logic. The timeout is disabled by
default.</para></listitem>
