integer. Configures how many virtual
terminals (VTs) to allocate by default
that, when switched to and are
previously unused,
"<code class="literal">autovt</code>" services are
automatically spawned on. These
services are instantiated from the
template unit
<code class="filename">autovt@.service</code>
for the respective VT TTY name,
for example, <code class="filename">autovt@tty4.service</code>. By
default,
<code class="filename">autovt@.service</code>

In other words, login prompts are started
dynamically as the user switches to
unused virtual terminals. Hence, this
parameter controls how many login
"<code class="literal">gettys</code>" are
available on the VTs. If a VT is
already used by some other subsystem
(for example, a graphical login), this
kind of activation will not be
attempted. Note that the VT configured
in <code class="varname">ReserveVT=</code> is
always subject to this kind of
activation, even if it is not one of
the VTs configured with the
<code class="varname">NAutoVTs=</code>
directive. Defaults to 6. When set to
0, automatic spawning of
"<code class="literal">autovt</code>" services is
disabled.</p></dd><dt id="ReserveVT="><span class="term"><code class="varname">ReserveVT=</code></span><a class="headerlink" title="Permalink to this term" href="#ReserveVT=">¶</a></dt><dd><p>Takes a positive

virtual terminal that shall
unconditionally be reserved for
<code class="filename">autovt@.service</code>
activation (see above). The VT
selected with this option will be
marked busy unconditionally, so that no
other subsystem will allocate it. This
functionality is useful to ensure that,
regardless of how many VTs are allocated
by other subsystems, one login
"<code class="literal">getty</code>" is always
available. Defaults to 6 (in other
words, there will always be a
"<code class="literal">getty</code>" available on
Alt-F6.). When set to 0, VT
reservation is
disabled.</p></dd><dt id="KillUserProcesses="><span class="term"><code class="varname">KillUserProcesses=</code></span><a class="headerlink" title="Permalink to this term" href="#KillUserProcesses=">¶</a></dt><dd><p>Takes a boolean

the user's last session ended). Defaults to
"<code class="literal">no</code>".</p><p>Note that setting

be killed when they log out
entirely. Processes of users listed in
<code class="varname">KillExcludeUsers=</code>
are excluded from being
killed. <code class="varname">KillExcludeUsers=</code>
defaults to "<code class="literal">root</code>"

user sessions correctly report the
idle status to the system. The system

no idle inhibitor lock is active,

otherwise, the specified action will

events. <code class="varname">HandlePowerKey=</code>

<code class="varname">HandleLidSwitch=</code>
default to "<code class="literal">suspend</code>".
<code class="varname">HandleHibernateKey=</code>

station, or if more than one display

actions triggered by the power and
sleep keys and the lid switch are
subject to inhibitor locks. These
settings take boolean arguments. If
"<code class="literal">off</code>", the inhibitor
locks taken by applications in order
to block the requested operation are
respected. If "<code class="literal">on</code>",
the requested operation is executed in
any
case. <code class="varname">PowerKeyIgnoreInhibited=</code>,
<code class="varname">SuspendKeyIgnoreInhibited=</code>

that the lid switch does not respect
suspend blockers by default, but the
power and sleep keys do.

the

optionally suffixed with the usual K, G,
M, and T suffixes, to the base 1024
(IEC). Alternatively, a numerical
percentage suffixed by "<code class="literal">%</code>"
may be specified, which sets the size
limit relative to the amount of
physical RAM. Defaults to 10%. Note
that this size is a safety limit
only. As each runtime directory is a
tmpfs file system, it will only consume
as much memory as is needed.

semaphores, shared memory and message
