+ initiates the resume from hibernation. It is instantiated with the

+
+ <para><filename>systemd-hibernate-resume</filename> only supports
+ the in-kernel hibernation implementation, known as
+ <ulink url="https://www.kernel.org/doc/Documentation/power/swsusp.txt">swsusp</ulink>.
+ Internally, it works by writing the major:minor of specified
+ device node to <filename>/sys/power/resume</filename>.</para>
+
+ <para>Failing to initiate a resume is not an error condition. It
+ may mean that there was no resume image (e. g. if the system has
+ been simply powered off and not hibernated). In such case, the
+ boot is ordinarily continued.</para>

+ <title>Description</title>
+
+ <para><filename>systemd-suspend.service</filename> is a system
+ service that is pulled in by <filename>suspend.target</filename>
+ and is responsible for the actual system suspend. Similarly,
+ <filename>systemd-hibernate.service</filename> is pulled in by
+ <filename>hibernate.target</filename> to execute the actual
+ hibernation. Finally,
+ <filename>systemd-hybrid-sleep.service</filename> is pulled in by
+ <filename>hybrid-sleep.target</filename> to execute hybrid
+ hibernation with system suspend.</para>
+
+ <para>Immediately before entering system suspend and/or
+ hibernation <filename>systemd-suspend.service</filename> (and the
+ other mentioned units, respectively) will run all executables in
+ <filename>/usr/lib/systemd/system-sleep/</filename> and pass two
+ arguments to them. The first argument will be
+ <literal>pre</literal>, the second either
+ <literal>suspend</literal>, <literal>hibernate</literal>, or
+ <literal>hybrid-sleep</literal> depending on the chosen action.
+ Immediately after leaving system suspend and/or hibernation the
+ same executables are run, but the first argument is now
+ <literal>post</literal>. All executables in this directory are
+ executed in parallel, and execution of the action is not continued
+ until all executables have finished.</para>
+
+ <para>Note that scripts or binaries dropped in
+ <filename>/usr/lib/systemd/system-sleep/</filename> are intended
+ for local use only and should be considered hacks. If applications
+ want to be notified of system suspend/hibernation and resume,
+ there are much nicer interfaces available.</para>
+
+ <para>Note that
+ <filename>systemd-suspend.service</filename>,
+ <filename>systemd-hibernate.service</filename>, and
+ <filename>systemd-hybrid-sleep.service</filename>
+ should never be executed directly. Instead, trigger system sleep
+ states with a command such as <literal>systemctl suspend</literal>
+ or similar.</para>
+
+ <para>Internally, this service will echo a string like
+ <literal>mem</literal> into <filename>/sys/power/state</filename>,
+ to trigger the actual system suspend. What exactly is written
+ where can be configured in the <literal>[Sleep]</literal> section
+ of <filename>/etc/systemd/sleep.conf</filename> or a
+ <filename>sleep.conf.d</filename> file. See

+ <para><filename>systemd-backlight@.service</filename> is a service
+ that restores the display backlight brightness at early boot and
+ saves it at shutdown. On disk, the backlight brightness is stored
+ in <filename>/var/lib/systemd/backlight/</filename>. During
+ loading, if the udev property <option>ID_BACKLIGHT_CLAMP</option> is
+ not set to false, the brightness is clamped to a value of at
+ least 1 or 5% of maximum brightness, whichever is greater. This
+ restriction will be removed when the kernel allows user space to
+ reliably set a brightness value which does not turn off the
+ display.</para>

+ <title>Description</title>
+
+ <para><command>systemd-firstboot</command> initializes the most
+ basic system settings interactively on the first boot, or
+ optionally non-interactively when a system image is created. The
+ following settings may be set up:</para>
+
+ <itemizedlist>
+ <listitem><para>The system locale, more specifically the two
+ locale variables <varname>LANG=</varname> and
+ <varname>LC_MESSAGES</varname></para></listitem>
+
+ <listitem><para>The system time zone</para></listitem>
+
+ <listitem><para>The system host name</para></listitem>
+
+ <listitem><para>The machine ID of the system</para></listitem>
+
+ <listitem><para>The root user's password</para></listitem>
+ </itemizedlist>
+
+ <para>Each of the fields may either be queried interactively by
+ users, set non-interactively on the tool's command line, or be
+ copied from a host system that is used to set up the system
+ image.</para>
+
+ <para>If a setting is already initialized, it will not be
+ overwritten and the user will not be prompted for the
+ setting.</para>
+
+ <para>Note that this tool operates directly on the file system and
+ does not involve any running system services, unlike
+ <citerefentry project='man-pages'><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>,
+ <citerefentry><refentrytitle>timedatectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ or
+ <citerefentry><refentrytitle>hostnamectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+ This allows <command>systemd-firstboot</command> to operate on
+ mounted but not booted disk images and in early boot. It is not
+ recommended to use <command>systemd-firstboot</command> on the
+ running system while it is up.</para>
+ </refsect1>

+ </varlistentry>
+

+ <title>Description</title>
+
+ <para><filename>systemd-fsck@.service</filename> and
+ <filename>systemd-fsck-root.service</filename> are services
+ responsible for file system checks. They are instantiated for each
+ device that is configured for file system checking.
+ <filename>systemd-fsck-root.service</filename> is responsible for
+ file system checks on the root file system, but only if the
+ root filesystem was not checked in the initramfs.
+ <filename>systemd-fsck@.service</filename> is used for all other
+ file systems and for the root file system in the initramfs.</para>
+
+ <para>These services are started at boot if
+ <option>passno</option> in <filename>/etc/fstab</filename> for the
+ file system is set to a value greater than zero. The file system
+ check for root is performed before the other file systems. Other
+ file systems may be checked in parallel, except when they are on
+ the same rotating disk.</para>
+
+ <para><filename>systemd-fsck</filename> does not know any details
+ about specific filesystems, and simply executes file system
+ checkers specific to each filesystem type
+ (<filename>/sbin/fsck.*</filename>). This helper will decide if
+ the filesystem should actually be checked based on the time since
+ last check, number of mounts, unclean unmount, etc.</para>
+
+ <para>If a file system check fails for a service without
+ <option>nofail</option>, emergency mode is activated, by isolating
+ to <filename>emergency.target</filename>.</para>

+ <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry>
+ for details. Saving/restoring the random seed across boots
+ increases the amount of available entropy early at boot. On disk
+ the random seed is stored in

+ <title>Description</title>
+
+ <para>At boot,
+ <citerefentry><refentrytitle>systemd-sysctl.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+ reads configuration files from the above directories to configure
+ <citerefentry project='man-pages'><refentrytitle>sysctl</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+ kernel parameters.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Configuration Format</title>
+
+ <para>The configuration files contain a list of variable
+ assignments, separated by newlines. Empty lines and lines whose
+ first non-whitespace character is <literal>#</literal> or
+ <literal>;</literal> are ignored.</para>
+
+ <para>Note that either <literal>/</literal> or
+ <literal>.</literal> may be used as separators within sysctl
+ variable names. If the first separator is a slash, remaining
+ slashes and dots are left intact. If the first separator is a dot,
+ dots and slashes are interchanged.
+ <literal>kernel.domainname=foo</literal> and
+ <literal>kernel/domainname=foo</literal> are equivalent and will
+ cause <literal>foo</literal> to be written to
+ <filename>/proc/sys/kernel/domainname</filename>. Either
+ <literal>net.ipv4.conf.enp3s0/200.forwarding</literal> or
+ <literal>net/ipv4/conf/enp3s0.200/forwarding</literal> may be used
+ to refer to
+ <filename>/proc/sys/net/ipv4/conf/enp3s0.200/forwarding</filename>.
+ </para>
+
+ <para>The settings configured with <filename>sysctl.d</filename>
+ files will be applied early on boot. The network
+ interface-specific options will also be applied individually for
+ each network interface as it shows up in the system. (More
+ specifically, <filename>net.ipv4.conf.*</filename>,
+ <filename>net.ipv6.conf.*</filename>,
+ <filename>net.ipv4.neigh.*</filename> and
+ <filename>net.ipv6.neigh.*</filename>).</para>
+
+ <para>Many sysctl parameters only become available when certain
+ kernel modules are loaded. Modules are usually loaded on demand,
+ e.g. when certain hardware is plugged in or network brought up.
+ This means that
+ <citerefentry><refentrytitle>systemd-sysctl.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+ which runs during early boot will not configure such parameters if
+ they become available after it has run. To set such parameters, it
+ is recommended to add an
+ <citerefentry><refentrytitle>udev</refentrytitle><manvolnum>7</manvolnum></citerefentry>
+ rule to set those parameters when they become available.
+ Alternatively, a slightly simpler and less efficient option is to
+ add the module to
+ <citerefentry><refentrytitle>modules-load.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
+ causing it to be loaded statically before sysctl settings are
+ applied (see example below).</para>

+
+ <para>This method applies settings when the module is
+ loaded. Please note that, unless the <filename>br_netfilter</filename>
+ module is loaded, bridged packets will not be filtered by
+ Netfilter (starting with kernel 3.18), so simply not loading the
+ module is sufficient to avoid filtering.</para>

+ <title>Description</title>
+
+ <para><command>systemd-sysusers</command> uses the files from
+ <filename>sysusers.d</filename> directory to create system users
+ and groups at package installation or boot time. This tool may be
+ used to allocate system users and groups only, it is not useful
+ for creating non-system users and groups, as it accesses
+ <filename>/etc/passwd</filename> and
+ <filename>/etc/group</filename> directly, bypassing any more
+ complex user databases, for example any database involving NIS or
+ LDAP.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Configuration Format</title>
+
+ <para>Each configuration file shall be named in the style of
+ <filename><replaceable>package</replaceable>.conf</filename> or
+ <filename><replaceable>package</replaceable>-<replaceable>part</replaceable>.conf</filename>.
+ The second variant should be used when it is desirable to make it
+ easy to override just this part of configuration.</para>
+
+ <para>The file format is one line per user or group containing
+ name, ID, GECOS field description and home directory:</para>
+
+ <programlisting># Type Name ID GECOS
+u httpd 440 "HTTP User"
+u authd /usr/bin/authd "Authorization user"
+g input - -
+m authd input
+u root 0 "Superuser" /root</programlisting>
+
+ <refsect2>
+ <title>Type</title>
+
+ <para>The type consists of a single letter. The following line
+ types are understood:</para>
+
+ <variablelist>
+ <varlistentry>
+ <term><varname>u</varname></term>
+ <listitem><para>Create a system user and group of the
+ specified name should they not exist yet. The user's primary
+ group will be set to the group bearing the same name. The
+ user's shell will be set to
+ <filename>/sbin/nologin</filename>, the home directory to
+ the specified home directory, or <filename>/</filename> if
+ none is given. The account will be created disabled, so that
+ logins are not allowed.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>g</varname></term>
+ <listitem><para>Create a system group of the specified name
+ should it not exist yet. Note that <varname>u</varname>
+ implicitly create a matching group. The group will be
+ created with no password set.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>m</varname></term>
+ <listitem><para>Add a user to a group. If the user or group
+ do not exist yet, they will be implicitly
+ created.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>r</varname></term>
+ <listitem><para>Add a range of numeric UIDs/GIDs to the pool
+ to allocate new UIDs and GIDs from. If no line of this type
+ is specified, the range of UIDs/GIDs is set to some
+ compiled-in default. Note that both UIDs and GIDs are
+ allocated from the same pool, in order to ensure that users
+ and groups of the same name are likely to carry the same
+ numeric UID and GID.</para></listitem>
+ </varlistentry>
+
+ </variablelist>
+ </refsect2>
+
+ <refsect2>
+ <title>Name</title>
+
+ <para>The name field specifies the user or group name. It should
+ be shorter than 31 characters and avoid any non-ASCII
+ characters, and not begin with a numeric character. It is
+ strongly recommended to pick user and group names that are
+ unlikely to clash with normal users created by the
+ administrator. A good scheme to guarantee this is by prefixing
+ all system and group names with the underscore, and avoiding too
+ generic names.</para>
+
+ <para>For <varname>m</varname> lines, this field should contain
+ the user name to add to a group.</para>
+
+ <para>For lines of type <varname>r</varname>, this field should
+ be set to <literal>-</literal>.</para>
+ </refsect2>
+
+ <refsect2>
+ <title>ID</title>
+
+ <para>For <varname>u</varname> and <varname>g</varname>, the
+ numeric 32-bit UID or GID of the user/group. Do not use IDs 65535
+ or 4294967295, as they have special placeholder meanings.
+ Specify <literal>-</literal> for automatic UID/GID allocation
+ for the user or group. Alternatively, specify an absolute path
+ in the file system. In this case, the UID/GID is read from the
+ path's owner/group. This is useful to create users whose UID/GID
+ match the owners of pre-existing files (such as SUID or SGID
+ binaries).</para>
+
+ <para>For <varname>m</varname> lines, this field should contain
+ the group name to add to a user to.</para>
+
+ <para>For lines of type <varname>r</varname>, this field should
+ be set to a UID/GID range in the format
+ <literal>FROM-TO</literal>, where both values are formatted as
+ decimal ASCII numbers. Alternatively, a single UID/GID may be
+ specified formatted as decimal ASCII numbers.</para>
+ </refsect2>
+
+ <refsect2>
+ <title>GECOS</title>
+
+ <para>A short, descriptive string for users to be created,
+ enclosed in quotation marks. Note that this field may not
+ contain colons.</para>
+
+ <para>Only applies to lines of type <varname>u</varname> and
+ should otherwise be left unset, or be set to
+ <literal>-</literal>.</para>
+ </refsect2>
+
+ <refsect2>
+ <title>Home Directory</title>
+
+ <para>The home directory for a new system user. If omitted,
+ defaults to the root directory. It is recommended to not
+ unnecessarily specify home directories for system users, unless
+ software strictly requires one to be set.</para>
+
+ <para>Only applies to lines of type <varname>u</varname> and
+ should otherwise be left unset, or be set to
+ <literal>-</literal>.</para>
+ </refsect2>
+
+ </refsect1>
+
+ <xi:include href="standard-conf.xml" xpointer="confd" />
+
+ <refsect1>
+ <title>Idempotence</title>
+
+ <para>Note that <command>systemd-sysusers</command> will do
+ nothing if the specified users or groups already exist, so
+ normally, there is no reason to override
+ <filename>sysusers.d</filename> vendor configuration, except to
+ block certain users or groups from being created.</para>

+ <title>Description</title>
+
+ <para><command>systemd-tmpfiles</command> uses the configuration
+ files from the above directories to describe the creation,
+ cleaning and removal of volatile and temporary files and
+ directories which usually reside in directories such as
+ <filename>/run</filename> or <filename>/tmp</filename>.</para>
+
+ <para>Volatile and temporary files and directories are those
+ located in <filename>/run</filename> (and its alias
+ <filename>/var/run</filename>), <filename>/tmp</filename>,
+ <filename>/var/tmp</filename>, the API file systems such as
+ <filename>/sys</filename> or <filename>/proc</filename>, as well
+ as some other directories below <filename>/var</filename>.</para>
+
+ <para>System daemons frequently require private runtime
+ directories below <filename>/run</filename> to place communication
+ sockets and similar in. For these, consider declaring them in
+ their unit files using <varname>RuntimeDirectory=</varname> (see
+ <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ for details), if this is feasible.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Configuration Format</title>
+
+ <para>Each configuration file shall be named in the style of
+ <filename><replaceable>package</replaceable>.conf</filename> or
+ <filename><replaceable>package</replaceable>-<replaceable>part</replaceable>.conf</filename>.
+ The second variant should be used when it is desirable to make it
+ easy to override just this part of configuration.</para>
+
+ <para>Files in <filename>/etc/tmpfiles.d</filename> override files
+ with the same name in <filename>/usr/lib/tmpfiles.d</filename> and
+ <filename>/run/tmpfiles.d</filename>. Files in
+ <filename>/run/tmpfiles.d</filename> override files with the same
+ name in <filename>/usr/lib/tmpfiles.d</filename>. Packages should
+ install their configuration files in
+ <filename>/usr/lib/tmpfiles.d</filename>. Files in
+ <filename>/etc/tmpfiles.d</filename> are reserved for the local
+ administrator, who may use this logic to override the
+ configuration files installed by vendor packages. All
+ configuration files are sorted by their filename in lexicographic
+ order, regardless of which of the directories they reside in. If
+ multiple files specify the same path, the entry in the file with
+ the lexicographically earliest name will be applied. All other
+ conflicting entries will be logged as errors. When two lines are
+ prefix and suffix of each other, then the prefix is always
+ processed first, the suffix later. Lines that take globs are
+ applied after those accepting no globs. If multiple operations
+ shall be applied on the same file, (such as ACL, xattr, file
+ attribute adjustments), these are always done in the same fixed
+ order. Otherwise, the files/directories are processed in the order
+ they are listed.</para>
+
+ <para>If the administrator wants to disable a configuration file
+ supplied by the vendor, the recommended way is to place a symlink
+ to <filename>/dev/null</filename> in
+ <filename>/etc/tmpfiles.d/</filename> bearing the same filename.
+ </para>
+
+ <para>The configuration format is one line per path containing
+ type, path, mode, ownership, age, and argument fields:</para>
+
+ <programlisting>#Type Path Mode UID GID Age Argument
+ d /run/user 0755 root root 10d -
+ L /tmp/foobar - - - - /dev/null</programlisting>
+
+ <para>Fields may be enclosed within quotes and contain C-style escapes.</para>
+
+ <refsect2>
+ <title>Type</title>
+
+ <para>The type consists of a single letter and optionally an
+ exclamation mark.</para>
+
+ <para>The following line types are understood:</para>
+
+ <variablelist>
+ <varlistentry>
+ <term><varname>f</varname></term>

+ <listitem><para>Create a subvolume if the path does not
+ exist yet, the file system supports subvolumes (btrfs), and
+ the system itself is installed into a subvolume
+ (specifically: the root directory <filename>/</filename> is
+ itself a subvolume). Otherwise, create a normal directory, in
+ the same way as <varname>d</varname>. A subvolume created
+ with this line type is not assigned to any higher-level
+ quota group. For that, use <varname>q</varname> or
+ <varname>Q</varname>, which allow creating simple quota
+ group hierarchies, see below.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>q</varname></term>
+ <listitem><para>Similar to <varname>v</varname>. However,
+ makes sure that the subvolume will be assigned to the same
+ higher-level quota groups as the subvolume it has been
+ created in. This ensures that higher-level limits and
+ accounting applied to the parent subvolume also include the
+ specified subvolume. On non-btrfs file systems, this line
+ type is identical to <varname>d</varname>. If the subvolume
+ already exists and is already assigned to one or more higher
+ level quota groups, no change to the quota hierarchy is
+ made. Also see <varname>Q</varname> below. See <citerefentry
+ project='die-net'><refentrytitle>btrfs-qgroup</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+ for details about the btrfs quota group
+ concept.</para></listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><varname>Q</varname></term>
+ <listitem><para>Similar to <varname>q</varname>. However,
+ instead of copying the higher-level quota group assignments
+ from the parent as-is, the lowest quota group of the parent
+ subvolume is determined that is not the leaf quota
+ group. Then, an "intermediary" quota group is inserted that
+ is one level below this level, and shares the same ID part
+ as the specified subvolume. If no higher-level quota group
+ exists for the parent subvolume, a new quota group at level
+ 255 sharing the same ID as the specified subvolume is
+ inserted instead. This new intermediary quota group is then
+ assigned to the parent subvolume's higher-level quota
+ groups, and the specified subvolume's leaf quota group is
+ assigned to it.</para>
+
+ <para>Effectively, this has a similar effect as
+ <varname>q</varname>, however introduces a new higher-level
+ quota group for the specified subvolume that may be used to
+ enforce limits and accounting to the specified subvolume and
+ children subvolume created within it. Thus, by creating
+ subvolumes only via <varname>q</varname> and
+ <varname>Q</varname>, a concept of "subtree quotas" is
+ implemented. Each subvolume for which <varname>Q</varname>
+ is set will get a "subtree" quota group created, and all
+ child subvolumes created within it will be assigned to
+ it. Each subvolume for which <varname>q</varname> is set
+ will not get such a "subtree" quota group, but it is ensured
+ that they are added to the same "subtree" quota group as their
+ immediate parents.</para>
+
+ <para>It is recommended to use
+ <varname>Q</varname> for subvolumes that typically contain
+ further subvolumes, and where it is desirable to have
+ accounting and quota limits on all child subvolumes
+ together. Examples for <varname>Q</varname> are typically
+ <filename>/home</filename> or
+ <filename>/var/lib/machines</filename>. In contrast,
+ <varname>q</varname> should be used for subvolumes that
+ either usually do not include further subvolumes or where no
+ accounting and quota limits are needed that apply to all
+ child subvolumes together. Examples for <varname>q</varname>
+ are typically <filename>/var</filename> or
+ <filename>/var/tmp</filename>. As with <varname>Q</varname>,
+ <varname>q</varname> has no effect on the quota group
+ hierarchy if the subvolume exists and already has at least
+ one higher-level quota group assigned.</para></listitem>

+ <title>Mode</title>
+
+ <para>The file access mode to use when creating this file or
+ directory. If omitted or when set to <literal>-</literal>, the
+ default is used: 0755 for directories, 0644 for all other file
+ objects. For <varname>z</varname>, <varname>Z</varname> lines,
+ if omitted or when set to <literal>-</literal>, the file access
+ mode will not be modified. This parameter is ignored for
+ <varname>x</varname>, <varname>r</varname>,
+ <varname>R</varname>, <varname>L</varname>, <varname>t</varname>,
+ and <varname>a</varname> lines.</para>
+
+ <para>Optionally, if prefixed with <literal>~</literal>, the
+ access mode is masked based on the already set access bits for
+ existing file or directories: if the existing file has all
+ executable bits unset, all executable bits are removed from the
+ new access mode, too. Similarly, if all read bits are removed
+ from the old access mode, they will be removed from the new
+ access mode too, and if all write bits are removed, they will be
+ removed from the new access mode too. In addition, the
+ sticky/SUID/SGID bit is removed unless applied to a
+ directory. This functionality is particularly useful in
+ conjunction with <varname>Z</varname>.</para>
+ </refsect2>
+
+ <refsect2>
+ <title>UID, GID</title>
+
+ <para>The user and group to use for this file or directory. This
+ may either be a numeric user/group ID or a user or group
+ name. If omitted or when set to <literal>-</literal>, the
+ default 0 (root) is used. For <varname>z</varname> and
+ <varname>Z</varname> lines, when omitted or when set to
+ <literal>-</literal>, the file ownership will not be
+ modified. These parameters are ignored for <varname>x</varname>,

+ <varname>a</varname> lines.</para>
+ </refsect2>
+
+ <refsect2>
+ <title>Age</title>
+ <para>The date field, when set, is used to decide what files to
+ delete when cleaning. If a file or directory is older than the
+ current time minus the age field, it is deleted. The field
+ format is a series of integers each followed by one of the
+ following suffixes for the respective time units:
+ <constant>s</constant>,
+ <constant>m</constant> or <constant>min</constant>,
+ <constant>h</constant>,
+ <constant>d</constant>,
+ <constant>w</constant>,
+ <constant>ms</constant>, and
+ <constant>us</constant>,
+ meaning seconds, minutes, hours, days, weeks,
+ milliseconds, and microseconds, respectively. Full names of the time units can
+ be used too.
+ </para>
+
+ <para>If multiple integers and units are specified, the time
+ values are summed. If an integer is given without a unit,
+ <constant>s</constant> is assumed.
+ </para>
+
+ <para>When the age is set to zero, the files are cleaned
+ unconditionally.</para>
+
+ <para>The age field only applies to lines starting with
+ <varname>d</varname>, <varname>D</varname>, <varname>e</varname>,
+ <varname>v</varname>, <varname>q</varname>,
+ <varname>Q</varname>, <varname>C</varname>, <varname>x</varname>
+ and <varname>X</varname>. If omitted or set to
+ <literal>-</literal>, no automatic clean-up is done.</para>
+
+ <para>If the age field starts with a tilde character
+ <literal>~</literal>, the clean-up is only applied to files and
+ directories one level inside the directory specified, but not
+ the files and directories immediately inside it.</para>
+ </refsect2>
+
+ <refsect2>
+ <title>Argument</title>
+
+ <para>For <varname>L</varname> lines determines the destination
+ path of the symlink. For <varname>c</varname> and
+ <varname>b</varname>, determines the major/minor of the device
+ node, with major and minor formatted as integers, separated by
+ <literal>:</literal>, e.g. <literal>1:3</literal>. For
+ <varname>f</varname>, <varname>F</varname>, and
+ <varname>w</varname>, the argument may be used to specify a short string that
+ is written to the file, suffixed by a newline. For
+ <varname>C</varname>, specifies the source file or
+ directory. For <varname>t</varname> and <varname>T</varname>,
+ determines extended attributes to be set. For
+ <varname>a</varname> and <varname>A</varname>, determines ACL
+ attributes to be set. For <varname>h</varname> and
+ <varname>H</varname>, determines the file attributes to
+ set. Ignored for all other lines.</para>

+ <title>Description</title>
+
+ <para><filename>systemd-update-done.service</filename> is a
+ service that is invoked as part of the first boot after the vendor
+ operating system resources in <filename>/usr</filename> have been
+ updated. This is useful to implement offline updates of
+ <filename>/usr</filename> which might require updates to
+ <filename>/etc</filename> or <filename>/var</filename> on the
+ following boot.</para>
+
+ <para><filename>systemd-update-done.service</filename> updates the
+ file modification time (mtime) of the stamp files
+ <filename>/etc/.updated</filename> and
+ <filename>/var/.updated</filename> to the modification time of the
+ <filename>/usr</filename> directory, unless the stamp files are
+ already newer.</para>
+
+ <para>Services that shall run after offline upgrades of
+ <filename>/usr</filename> should order themselves before
+ <filename>systemd-update-done.service</filename>, and use the
+ <varname>ConditionNeedsUpdate=</varname> (see
+ <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>)
+ condition to make sure to run when <filename>/etc</filename> or
+ <filename>/var</filename> are older than <filename>/usr</filename>
+ according to the modification times of the files described above.
+ This requires that updates to <filename>/usr</filename> are always
+ followed by an update of the modification time of
+ <filename>/usr</filename>, for example by invoking
+ <citerefentry project='man-pages'><refentrytitle>touch</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ on it.</para>

+ the optional <replaceable>TTY</replaceable> parameter is provided — a specific one. When the system is booting up
+ it's called by <citerefentry><command>udev</command></citerefentry> during vtconsole subsystem initialization.
+ <productname>Systemd</productname> also calls it internally as needed via
+ <filename>systemd-vconsole-setup.service</filename>. The helper calls
+ <citerefentry project='mankier'><refentrytitle>loadkeys</refentrytitle><manvolnum>1</manvolnum></citerefentry> and
+ <citerefentry project='die-net'><refentrytitle>setfont</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+ internally.
+ </para>
+
+ <para>
+ You may want to use this helper whenever you change <filename>vconsole.conf</filename> to
+ refresh the settings on your consoles — either through the <command>systemctl restart</command> /
+ <command>systemctl start</command> command or directly through the executable.

+ <title>Description</title>
+
+ <para>The <filename>/etc/vconsole.conf</filename> file configures
+ the virtual console, i.e. keyboard mapping and console font. It is
+ applied at boot by udev using <filename>90-vconsole.rules</filename> file.
+ You can safely mask this file if you want to avoid this kind of initialization.
+ </para>
+
+ <para>The basic file format of the
+ <filename>vconsole.conf</filename> is a newline-separated list of
+ environment-like shell-compatible variable assignments. It is
+ possible to source the configuration from shell scripts, however,
+ beyond mere variable assignments no shell features are supported,
+ allowing applications to read the file without implementing a
+ shell compatible execution engine.</para>
+
+ <para>Note that the kernel command line options
+ <varname>vconsole.keymap=</varname>,
+ <varname>vconsole.keymap_toggle=</varname>,
+ <varname>vconsole.font=</varname>,
+ <varname>vconsole.font_map=</varname>,
+ <varname>vconsole.font_unimap=</varname> may be used
+ to override the console settings at boot.</para>
+
+ <para>Depending on the operating system other configuration files
+ might be checked for configuration of the virtual console as well,
+ however only as fallback.</para>
