It is common - that services are configured to be activated via more than one - mechanism at the same time. An example for systemd: - <filename>bluetoothd.service</filename> might get activated either - when Bluetooth hardware is plugged in, or when an application - accesses its programming interfaces via D-Bus. Or, a print server - daemon might get activated when traffic arrives at an IPP port, or - when a printer is plugged in, or when a file is queued in the - printer spool directory. Even for services that are intended to be - started on system bootup unconditionally, it is a good idea to - implement some of the various activation schemes outlined below, - in order to maximize parallelization. If a daemon implements a - D-Bus service or listening socket, implementing the full bus and - socket activation scheme allows starting of the daemon with its - clients in parallel (which speeds up boot-up), since all its - communication channels are established already, and no request is - lost because client requests will be queued by the bus system (in - case of D-Bus) or the kernel (in case of sockets) until the - activation is completed.</para> - - <refsect2> - <title>Activation on Boot</title> - - <para>Old-style daemons are usually activated exclusively on - boot (and manually by the administrator) via SysV init scripts, - as detailed in the <ulink - url="http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html">LSB - Linux Standard Base Core Specification</ulink>. This method of - activation is supported ubiquitously on GNU/Linux init systems, both - old-style and new-style systems.

In a - socket-based activation scheme, the creation and binding of the - listening socket as primary communication channel of daemons to - local (and sometimes remote) clients is moved out of the daemon - code and into the init system. Based on per-daemon - configuration, the init system installs the sockets and then - hands them off to the spawned process as soon as the respective - daemon is to be started. Optionally, activation of the service - can be delayed until the first inbound traffic arrives at the - socket to implement on-demand activation of daemons. However, - the primary advantage of this scheme is that all providers and - all consumers of the sockets can be started in parallel as soon - as all sockets are established. In addition to that, daemons can - be restarted with losing only a minimal number of client - transactions, or even any client request at all (the latter is - particularly true for state-less protocols, such as DNS or - syslog), because the socket stays bound and accessible during - the restart, and all requests are queued while the daemon cannot - process them.</para> - - <para>New-style daemons which support socket activation must be - able to receive their sockets from the init system instead of - creating and binding them themselves. For details about the - programming interfaces for this scheme provided by systemd, see - <citerefentry><refentrytitle>sd_listen_fds</refentrytitle><manvolnum>3</manvolnum></citerefentry> - and - <citerefentry><refentrytitle>sd-daemon</refentrytitle><manvolnum>3</manvolnum></citerefentry>. - For details about porting existing daemons to socket-based - activation, see below.

It is - recommended to place a - <varname>WantedBy=sockets.target</varname> directive in the - <literal>[Install]</literal> section to automatically add such a - dependency on installation of a socket unit. Unless - <varname>DefaultDependencies=no</varname> is set, the necessary - ordering dependencies are implicitly created for all socket - units.

This is configured in D-Bus - service files (not to be confused with systemd service unit - files!). To ensure that D-Bus uses systemd to start-up and - maintain the daemon, use the <varname>SystemdService=</varname> - directive in these service files to configure the matching - systemd service for a D-Bus service. e.g.: For a D-Bus service - whose D-Bus activation file is named - <filename>org.freedesktop.RealtimeKit.service</filename>, make - sure to set - <varname>SystemdService=rtkit-daemon.service</varname> in that - file to bind it to the systemd service - <filename>rtkit-daemon.service</filename>. This is needed to - make sure that the daemon is started in a race-free fashion when - activated via multiple mechanisms simultaneously.</para> - </refsect2> - - <refsect2> - <title>Device-Based Activation</title> - - <para>Often, daemons that manage a particular type of hardware - should be activated only when the hardware of the respective - kind is plugged in or otherwise becomes available. In a - new-style init system, it is possible to bind activation to - hardware plug/unplug events. In systemd, kernel devices - appearing in the sysfs/udev device tree can be exposed as units - if they are tagged with the string <literal>systemd</literal>. - Like any other kind of unit, they may then pull in other units - when activated (i.e. plugged in) and thus implement device-based - activation. systemd dependencies may be encoded in the udev - database via the <varname>SYSTEMD_WANTS=</varname> property. See - <citerefentry><refentrytitle>systemd.device</refentrytitle><manvolnum>5</manvolnum></citerefentry> - for details. Often, it is nicer to pull in services from devices - only indirectly via dedicated targets. Example: Instead of - pulling in <filename>bluetoothd.service</filename> from all the - various bluetooth dongles and other hardware available, pull in - bluetooth.target from them and - <filename>bluetoothd.service</filename> from that target. This - provides for nicer abstraction and gives administrators the - option to enable <filename>bluetoothd.service</filename> via - controlling a <filename>bluetooth.target.wants/</filename> - symlink uniformly with a command like <command>enable</command> - of - <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry> - instead of manipulating the udev ruleset.</para> - </refsect2> - - <refsect2> - <title>Path-Based Activation</title> - - <para>Often, runtime of daemons processing spool files or - directories (such as a printing system) can be delayed until - these file system objects change state, or become non-empty. - New-style init systems provide a way to bind service activation - to file system changes. systemd implements this scheme via - path-based activation configured in <filename>.path</filename> - units, as outlined in - <citerefentry><refentrytitle>systemd.path</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para> - </refsect2> - - <refsect2> - <title>Timer-Based Activation</title> - - <para>Some daemons that implement clean-up jobs that are - intended to be executed in regular intervals benefit from - timer-based activation.

However, there are often simpler or - better alternatives, or they can be put together of combinations - of the schemes above. Example: Sometimes, it appears useful to - start daemons or <filename>.socket</filename> units when a - specific IP address is configured on a network interface, - because network sockets shall be bound to the address. However, - an alternative to implement this is by utilizing the Linux - <constant>IP_FREEBIND</constant> socket option, as accessible - via <varname>FreeBind=yes</varname> in systemd socket files (see - <citerefentry><refentrytitle>systemd.socket</refentrytitle><manvolnum>5</manvolnum></citerefentry> - for details). This option, when enabled, allows sockets to be - bound to a non-local, not configured IP address, and hence - allows bindings to a particular IP address before it actually - becomes available, making such an explicit dependency to the - configured address redundant. Another often suggested trigger - for service activation is low system load. However, here too, a - more convincing approach might be to make proper use of features - of the operating system, in particular, the CPU or I/O scheduler - of Linux. Instead of scheduling jobs from userspace based on - monitoring the OS scheduler, it is advisable to leave the - scheduling of processes to the OS scheduler itself. systemd - provides fine-grained access to the CPU and I/O schedulers. If a - process executed by the init system shall not negatively impact - the amount of CPU or I/O bandwidth available to other processes, - it should be configured with - <varname>CPUSchedulingPolicy=idle</varname> and/or - <varname>IOSchedulingClass=idle</varname>. Optionally, this may - be combined with timer-based activation to schedule background - jobs during runtime and with minimal impact on the system, and - remove it from the boot phase itself.</para> - </refsect2> - - </refsect1> - <refsect1> - <title>Integration with Systemd</title> - - <refsect2> - <title>Writing Systemd Unit Files</title> - - <para>When writing systemd unit files, it is recommended to - consider the following suggestions:</para> - - <orderedlist> - <listitem><para>If possible, do not use the - <varname>Type=forking</varname> setting in service files.

If a - file path refers to an executable script, a <literal>_COMM=</literal> - match for the script name is added to the query. If a file path - refers to a device node, <literal>_KERNEL_DEVICE=</literal> matches for - the kernel name of the device and for each of its ancestor devices is - added to the query. Symbolic links are dereferenced, kernel names are - synthesized, and parent devices are identified from the environment at - the time of the query. In general, a device node is the best proxy for - an actual device, as log entries do not usually contain fields that - identify an actual device. For the resulting log entries to be correct - for the actual device, the relevant parts of the environment at the time - the entry was logged, in particular the actual device corresponding to - the device node, must have been the same as those at the time of the - query.

The connection object is associated - with the calling thread. Each time the function is invoked from - the same thread, the same object is returned, but its reference - count is increased by one, as long as at least one reference is - kept. When the last reference to the connection is dropped (using - the - <citerefentry><refentrytitle>sd_bus_unref</refentrytitle><manvolnum>3</manvolnum></citerefentry> - call), the connection is terminated. Note that the connection is - not automatically terminated when the associated thread ends.

Also, queued but unread or unwritten messages keep the - bus referenced, see below.</para> - - <para><function>sd_bus_default_user()</function> returns a user - bus connection object associated with the calling thread. - <function>sd_bus_default_system()</function> is similar, but - connects to the system bus.

Note that log messages written using this function are generally not - expected to end in a new-line character. However, as all trailing whitespace (including spaces, new-lines, - tabulators and carriage returns) are automatically stripped from the logged string, it is acceptable to specify one - (or more).

If the unit - name without the type suffix qualifies as valid user name it is used directly, otherwise a name incorporating a - hash of it is used. If a statically allocated user or group of the configured name already exists, it is used - and no dynamic user/group is allocated. Dynamic users/groups are allocated from the UID/GID range - 61184…65519. It is recommended to avoid this range for regular system or login users. At any point in time - each UID/GID from this range is only assigned to zero or one dynamically allocated users/groups in - use. However, UID/GIDs are recycled after a unit is terminated. Care should be taken that any processes running - as part of a unit for which dynamic users/groups are enabled do not leave files or directories owned by these - users/groups around, as a different unit might get the same UID/GID assigned later on, and thus gain access to - these files or directories.

Since <filename>/tmp</filename> and <filename>/var/tmp</filename> are usually the only - world-writable directories on a system this ensures that a unit making use of dynamic user/group allocation - cannot leave files around after unit termination. Moreover <varname>ProtectSystem=strict</varname> and - <varname>ProtectHome=read-only</varname> are implied, thus prohibiting the service to write to arbitrary file - system locations. In order to allow the service to write to certain directories, they have to be whitelisted - using <varname>ReadWritePaths=</varname>, but care must be taken so that UID/GID recycling doesn't - create security issues involving files created by the service.

With - <varname>Type=</varname><option>oneshot</option>, systemd waits - until the start action has completed before it considers the - unit to be active, so dependencies start only after the start - action has succeeded.

Set - <varname>Type=</varname><option>forking</option> in the - service's unit file to support this mode of operation. systemd - will consider the service to be in the process of initialization - while the original program is still running. Once it exits - successfully and at least a process remains (and - <varname>RemainAfterExit=</varname><option>no</option>), the - service is considered started.</para> - - <para>Often, a traditional daemon only consists of one process. - Therefore, if only one process is left after the original - process terminates, systemd will consider that process the main - process of the service. In that case, the - <varname>$MAINPID</varname> variable will be available in - <varname>ExecReload=</varname>, <varname>ExecStop=</varname>, - etc.</para> - - <para>In case more than one process remains, systemd will be - unable to determine the main process, so it will not assume - there is one.

For - example, <filename>reboot.target</filename> specifies - <varname>Alias=ctrl-alt-del.target</varname>, so when enabled it will be invoked whenever - CTRL+ALT+DEL is pressed. Alias names may be used in commands like <command>enable</command>, - <command>disable</command>, <command>start</command>, <command>stop</command>, - <command>status</command>, …, and in unit dependency directives <varname>Wants=</varname>, - <varname>Requires=</varname>, <varname>Before=</varname>, <varname>After=</varname>, …, with the - limitation that aliases specified through <varname>Alias=</varname> are only effective when the - unit is enabled. Aliases cannot be used with the <command>preset</command> command.</para> - - <para>Along with a unit file <filename>foo.service</filename>, the directory - <filename>foo.service.wants/</filename> may exist. All unit files symlinked from such a - directory are implicitly added as dependencies of type <varname>Wants=</varname> to the unit. - This is useful to hook units into the start-up of other units, without having to modify their - unit files. For details about the semantics of <varname>Wants=</varname>, see below. The - preferred way to create symlinks in the <filename>.wants/</filename> directory of a unit file is - with the <command>enable</command> command of the - <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry> - tool which reads information from the [Install] section of unit files (see below). A similar - functionality exists for <varname>Requires=</varname> type dependencies as well, the directory - suffix is <filename>.requires/</filename> in this case.</para> - - <para>Along with a unit file <filename>foo.service</filename>, a "drop-in" directory - <filename>foo.service.d/</filename> may exist. All files with the suffix - <literal>.conf</literal> from this directory will be parsed after the file itself is - parsed. This is useful to alter or add configuration settings for a unit, without having to - modify unit files. Each drop-in file must have appropriate section headers. Note that for - instantiated units, this logic will first look for the instance <literal>.d/</literal> - subdirectory and read its <literal>.conf</literal> files, followed by the template - <literal>.d/</literal> subdirectory and the <literal>.conf</literal> files there. Also note that - settings from the <literal>[Install]</literal> section are not honored in drop-in unit files, - and have no effect.</para> - - <para>In addition to <filename>/etc/systemd/system</filename>, the drop-in <literal>.d</literal> - directories for system services can be placed in <filename>/usr/lib/systemd/system</filename> or - <filename>/run/systemd/system</filename> directories. Drop-in files in <filename>/etc</filename> - take precedence over those in <filename>/run</filename> which in turn take precedence over those - in <filename>/usr/lib</filename>. Drop-in files under any of these directories take precedence - over unit files wherever located.</para> - - <!-- Note that we do not document .include here, as we consider it mostly obsolete, and want - people to use .d/ drop-ins instead. --> - - <para>Some unit names reflect paths existing in the file system - namespace. Example: a device unit - <filename>dev-sda.device</filename> refers to a device with the - device node <filename noindex='true'>/dev/sda</filename> in the - file system namespace. If this applies, a special way to escape - the path name is used, so that the result is usable as part of a - filename. Basically, given a path, "/" is replaced by "-", and all - other characters which are not ASCII alphanumerics are replaced by - C-style "\x2d" escapes (except that "_" is never replaced and "." - is only replaced when it would be the first character in the - escaped path). The root directory "/" is encoded as single dash, - while otherwise the initial and ending "/" are removed from all - paths during transformation. This escaping is reversible. Properly - escaped paths can be generated using the - <citerefentry><refentrytitle>systemd-escape</refentrytitle><manvolnum>1</manvolnum></citerefentry> - command.</para> - - <para>Optionally, units may be instantiated from a - template file at runtime. This allows creation of - multiple units from a single configuration file. If - systemd looks for a unit configuration file, it will - first search for the literal unit name in the - file system. If that yields no success and the unit - name contains an <literal>@</literal> character, systemd will look for a - unit template that shares the same name but with the - instance string (i.e. the part between the <literal>@</literal> character - and the suffix) removed. Example: if a service - <filename>getty@tty3.service</filename> is requested - and no file by that name is found, systemd will look - for <filename>getty@.service</filename> and - instantiate a service from that configuration file if - it is found.</para> - - <para>To refer to the instance string from within the - configuration file you may use the special <literal>%i</literal> - specifier in many of the configuration options. See below for - details.</para> - - <para>If a unit file is empty (i.e. has the file size 0) or is - symlinked to <filename>/dev/null</filename>, its configuration - will not be loaded and it appears with a load state of - <literal>masked</literal>, and cannot be activated.

NB: ordering and requirement - dependencies are orthogonal. If only a requirement dependency - exists between two units (e.g. <filename>foo.service</filename> - requires <filename>bar.service</filename>), but no ordering - dependency (e.g. <filename>foo.service</filename> after - <filename>bar.service</filename>) and both are requested to start, - they will be started in parallel. It is a common pattern that both - requirement and ordering dependencies are placed between two - units. Also note that the majority of dependencies are implicitly - created and maintained by systemd. In most cases, it should be - unnecessary to declare additional dependencies manually, however - it is possible to do this.</para> - - <para>Application programs and units (via dependencies) may - request state changes of units. In systemd, these requests are - encapsulated as 'jobs' and maintained in a job queue. Jobs may - succeed or can fail, their execution is ordered based on the - ordering dependencies of the units they have been scheduled - for.</para> - - <para>On boot systemd activates the target unit - <filename>default.target</filename> whose job is to activate - on-boot services and other on-boot units by pulling them in via - dependencies. Usually, the unit name is just an alias (symlink) for - either <filename>graphical.target</filename> (for fully-featured - boots into the UI) or <filename>multi-user.target</filename> (for - limited console-only boots for use in embedded or server - environments, or similar; a subset of graphical.target). However, - it is at the discretion of the administrator to configure it as an - alias to any other target unit. See - <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry> - for details about these target units.</para> - - <para>Processes systemd spawns are placed in individual Linux - control groups named after the unit which they belong to in the - private systemd hierarchy. (see <ulink - url="https://www.kernel.org/doc/Documentation/cgroups/cgroups.txt">cgroups.txt</ulink> - for more information about control groups, or short "cgroups"). - systemd uses this to effectively keep track of processes. Control - group information is maintained in the kernel, and is accessible - via the file system hierarchy (beneath - <filename>/sys/fs/cgroup/systemd/</filename>), or in tools such as - <citerefentry project='man-pages'><refentrytitle>systemd-cgls</refentrytitle><manvolnum>1</manvolnum></citerefentry> - or - <citerefentry project='man-pages'><refentrytitle>ps</refentrytitle><manvolnum>1</manvolnum></citerefentry> - (<command>ps xawf -eo pid,user,cgroup,args</command> is - particularly useful to list all processes and the systemd units - they belong to.).</para> - - <para>systemd is compatible with the SysV init system to a large - degree: SysV init scripts are supported and simply read as an - alternative (though limited) configuration file format. The SysV - <filename>/dev/initctl</filename> interface is provided, and - compatibility implementations of the various SysV client tools are - available. In addition to that, various established Unix - functionality such as <filename>/etc/fstab</filename> or the - <filename>utmp</filename> database are supported.</para> - - <para>systemd has a minimal transaction system: if a unit is - requested to start up or shut down it will add it and all its - dependencies to a temporary transaction. Then, it will verify if - the transaction is consistent (i.e. whether the ordering of all - units is cycle-free). If it is not, systemd will try to fix it up, - and removes non-essential jobs from the transaction that might - remove the loop. Also, systemd tries to suppress non-essential - jobs in the transaction that would stop a running service. Finally - it is checked whether the jobs of the transaction contradict jobs - that have already been queued, and optionally the transaction is - aborted then. If all worked out and the transaction is consistent - and minimized in its impact it is merged with all already - outstanding jobs and added to the run queue. Effectively this - means that before executing a requested operation, systemd will - verify that it makes sense, fixing it if possible, and only - failing if it really cannot work.</para> - - <para>Systemd contains native implementations of various tasks - that need to be executed as part of the boot process.
