'set-property' has been primarly designed to change some properties of
*active* units.
However it can easily work on inactive units as well. In that case
changes are only saved in a drop-in for futur uses and changes will be
effective when unit will be started.
Actually it already works on inactive units but that was not
documented and not fully supported. Indeed the inactive units had to
be known by the manager otherwise it was reported as not loaded:
$ systemctl status my-test.service
* my-test.service - My Testing Unit
Loaded: loaded (/etc/systemd/system/my-test.service; static; vendor preset: disabled)
Drop-In: /etc/systemd/system/my-test.service.d
Active: inactive (dead)
$ systemctl set-property my-test.service MemoryLimit=1000000
Failed to set unit properties on my-test.service: Unit my-test.service is not loaded.
[ Note: that the unit load state reported by the 'status' command
might be confusing since it claimed the unit as loaded but
'set-property' reported the contrary. ]
One can possibily workaround this by making the unit a dependency of
another active unit so the manager will keep it around:
$ systemctl add-wants multi-user.target my-test.service
Created symlink from /etc/systemd/system/multi-user.target.wants/my-test.service to /etc/systemd/system/my-test.service.
$ systemctl set-property my-test.service MemoryLimit=1000000
$ systemctl status my-test.service
* my-test.service - My Testing Unit
Loaded: loaded (/etc/systemd/system/my-test.service; enabled; vendor preset: disabled)
Drop-In: /etc/systemd/system/my-test.service.d
`-50-MemoryLimit.conf
Active: inactive (dead)
This patch simply forces 'SetUnitProperties()' to load the unit if
it's not already the case.
It also documents the fact that 'set-property' can be used on inactive
units.

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

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

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

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

<para>When used with <command>kill</command>, choose which

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

<para>Enable one or more unit files or unit file instances,
|

as specified on the command line. This will create a number
|

of symlinks as encoded in the <literal>[Install]</literal>
|
||
sections of the unit files. After the symlinks have been
|
||
created, the systemd configuration is reloaded (in a way that

is equivalent to <command>daemon-reload</command>) to ensure
|
||
the changes are taken into account immediately. Note that
|

this does <emphasis>not</emphasis> have the effect of also

starting any of the units being enabled. If this
|
||
is desired, either <option>--now</option> should be used
|
||
together with this command, or an additional <command>start</command>
|
||
command must be invoked for the unit. Also note that, in case of
|
||
instance enablement, symlinks named the same as instances
|

are created in the install location, however they all point to the

same template unit file.</para>

<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>
|
||
|
||
<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>,
|
||
or <option>--global</option> is specified, this enables the unit
|
||
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>

<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, 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
|
||
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 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.
|
||
</para>
|
||
|
||
<para>For unit file commands, the specified
|
||
<replaceable>NAME</replaceable> should be the full name of the
|
||
unit file, or the absolute path to the unit file:
|
||
<programlisting># systemctl enable foo.service</programlisting>
|
||
or
|
||
<programlisting># systemctl link /path/to/foo.service</programlisting>
