When "preset" was executed for a unit without install info, we'd warn similarly as for "enable" and "disable". But "preset" is usually called for all units, because the preset files are provided by the distribution, and the units are under control of individual programs, and it's reasonable to call "preset" for all units rather then try to do it only for the ones that can be installed. We also don't warn about missing info for "preset-all". Thus it seems reasonable to silently ignore units w/o install info when presetting. (In addition, when more than one unit was specified, we'd issue the warning only if none of them had install info. But this is probably something to fix for enable/disable too.)

<para>If <literal>fail</literal> is specified and a requested

operation conflicts with a pending job (more specifically:

job or vice versa), cause the operation to fail.</para>
|

<para>If <literal>replace</literal> (the default) is

specified, any conflicting pending job will be replaced, as

necessary.</para>
|

<para>If <literal>replace-irreversibly</literal> is specified,

operate like <literal>replace</literal>, but also mark the new

<para><literal>isolate</literal> is only valid for start

<command>isolate</command> command is used.</para>

<para><literal>flush</literal> will cause all queued jobs to

be canceled when the new job is enqueued.</para>
|

|

<para>If <literal>ignore-dependencies</literal> is specified,

then all unit dependencies are ignored for this new job and
|
||
the operation is executed immediately. If passed, no required
|
||
units of the unit passed will be pulled in, and no ordering
|
||
dependencies will be honored. This is mostly a debugging and
|
||
rescue tool for the administrator and should not be used by
|
||
applications.</para>
|
||
|
||
<para><literal>ignore-requirements</literal> is similar to
|
||
<literal>ignore-dependencies</literal>, but only causes the
|
||
requirement dependencies to be ignored, the ordering

processes to send a signal to. Must be one of
|
||
<option>main</option>, <option>control</option> or
|
||
<option>all</option> to select whether to kill only the main
|
||
process, the control process or all processes of the
|
||
unit. The main process of the unit is the one that defines
|
||
the life-time of it. A control process of a unit is one that
|
||
is invoked by the manager to induce state changes of it. For
|
||
example, all processes started due to the
|
||
<varname>ExecStartPre=</varname>,
|
||
<varname>ExecStop=</varname> or
|
||
<varname>ExecReload=</varname> settings of service units are
|
||
control processes. Note that there is only one control
|
||
process per unit at a time, as only one state change is
|
||
executed at a time. For services of type
|
||
<varname>Type=forking</varname>, the initial process started
|
||
by the manager for <varname>ExecStart=</varname> is a
|
||
control process, while the process ultimately forked off by
|
||
that one is then considered the main process of the unit (if
|
||
it can be determined). This is different for service units
|
||
of other types, where the process forked off by the manager
|
||
for <varname>ExecStart=</varname> is always the main process
|
||
itself. A service unit consists of zero or one main process,
|
||
zero or one control process plus any number of additional
|
||
processes. Not all unit types manage processes of these
|
||
types however. For example, for mount units, control processes
|
||
are defined (which are the invocations of
|
||
<filename>&MOUNT_PATH;</filename> and
|
||
<filename>&UMOUNT_PATH;</filename>), but no main process
|

is defined. If omitted, defaults to

together with this command, or an additional <command>start</command>
|

command must be invoked for the unit. Also note that, in case of

<para>Note that this operation creates only the suggested
|
||
symlinks for the units. While this command is the
|
||
recommended way to manipulate the unit configuration
|
||
directory, the administrator is free to make additional
|
||
changes manually by placing or removing symlinks in the
|
||
directory. This is particularly useful to create
|
||
configurations that deviate from the suggested default
|
||
installation. In this case, the administrator must make sure
|

to invoke <command>daemon-reload</command> manually as
|

necessary to ensure the changes are taken into account.

<para>Enabling units should not be confused with starting

(activating) units, as done by the <command>start</command>

command. Enabling and starting units is orthogonal: units
|
||
may be enabled without being started and started without
|
||
being enabled. Enabling simply hooks the unit into various
|
||
suggested places (for example, so that the unit is
|
||
automatically started on boot or when a particular kind of
|
||
hardware is plugged in). Starting actually spawns the daemon
|
||
process (in case of service units), or binds the socket (in
|

case of socket units), and so on.</para>

<para>Depending on whether <option>--system</option>,

<option>--user</option>, <option>--runtime</option>,

for the system, for the calling user only, for only this boot of

||
the system, or for all future logins of all users, or only this

boot. Note that in the last case, no systemd daemon

configuration is reloaded.</para>

<listitem>

<para>Switches to a different root directory and executes a

||
new system manager process below it. This is intended for
|
||
usage in initial RAM disks ("initrd"), and will transition
|
||
from the initrd's system manager process (a.k.a. "init"
|
||
process) to the main system manager process. This call takes two
|
||
arguments: the directory that is to become the new root directory, and
|
||
the path to the new system manager binary below it to
|
||
execute as PID 1. If the latter is omitted or the empty
|
||
string, a systemd binary will automatically be searched for
|
||
and used as init. If the system manager path is omitted or
|
||
equal to the empty string, the state of the initrd's system
|
||
manager process is passed to the main system manager, which
|
||
allows later introspection of the state of the services
|
||
involved in the initrd boot.</para>

<title>Parameter Syntax</title>
|
||
|
||
<para>Unit commands listed above take either a single unit name (designated as <replaceable>NAME</replaceable>),
|
||
or multiple unit specifications (designated as <replaceable>PATTERN</replaceable>...). In the first case, the
|
||
unit name with or without a suffix must be given. If the suffix is not specified (unit name is "abbreviated"),
|
||
systemctl will append a suitable suffix, <literal>.service</literal> by default, and a type-specific suffix in
|
||
case of commands which operate only on specific unit types. For example,
|
||
<programlisting># systemctl start sshd</programlisting> and
|
||
<programlisting># systemctl start sshd.service</programlisting>
|
||
are equivalent, as are
|
||
<programlisting># systemctl isolate default</programlisting>
|
||
and
|
||
<programlisting># systemctl isolate default.target</programlisting>
|
||
Note that (absolute) paths to device nodes are automatically converted to device unit names, and other (absolute)
|
||
paths to mount unit names.
|
||
<programlisting># systemctl status /dev/sda
|
||
# systemctl status /home</programlisting>
|
||
are equivalent to:
|
||
<programlisting># systemctl status dev-sda.device
|
||
# systemctl status home.mount</programlisting>
|
||
In the second case, shell-style globs will be matched against the primary names of all currently loaded units;
|
||
literal unit names, with or without a suffix, will be treated as in the first case. This means that literal unit
|
||
names always refer to exactly one unit, but globs may match zero units and this is not considered an
|
||
error.</para>
|
||
|
||
<para>Glob patterns use
|
||
<citerefentry project='man-pages'><refentrytitle>fnmatch</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
|
||
so normal shell-style globbing rules are used, and
|
||
<literal>*</literal>, <literal>?</literal>,
|
||
<literal>[]</literal> may be used. See
|
||
<citerefentry project='man-pages'><refentrytitle>glob</refentrytitle><manvolnum>7</manvolnum></citerefentry>
|
||
for more details. The patterns are matched against the primary names of
|
||
currently loaded units, and patterns which do not match anything
|
||
are silently skipped. For example:
|
||
<programlisting># systemctl stop sshd@*.service</programlisting>
|
||
will stop all <filename>sshd@.service</filename> instances. Note that alias names of units, and units that aren't
|
||
loaded are not considered for glob expansion.
|
||
</para>
|
||
|
||
<para>For unit file commands, the specified <replaceable>NAME</replaceable> should be the name of the unit file
|
||
(possibly abbreviated, see above), or the absolute path to the unit file:
|
||
<programlisting># systemctl enable foo.service</programlisting>
|
||
or
|
||
<programlisting># systemctl link /path/to/foo.service</programlisting>
