</refsect1>
<refsect1>
<title>Options</title>
<para>All options are configured in the
<literal>[Login]</literal> section:</para>
<variablelist>
<varlistentry>
<term><varname>NAutoVTs=</varname></term>
<listitem><para>Takes a positive
integer. How many virtual terminals to
allocate by default and when switched
to autospawn <literal>autovt</literal>
services on (if they are otherwise
unused). These services are
instantiated from a template of
<filename>autovt@.service</filename>
with the virtual terminal TTY name,
e.g. <filename>autovt@tty4.service</filename>. By
default
<filename>autovt@.service</filename>
is linked to
<filename>getty@.service</filename>,
i.e. login prompts are started
dynamically as the user switches to
unused virtual terminals, and this
parameter hence controls how many
gettys are available on the virtual
terminals. Defaults to 6. When set to
0, automatic spawning of
<literal>autovt</literal> services is
disabled.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>KillUserProcesses=</varname></term>
<listitem><para>Takes a boolean
argument. Configures whether the
processes of a user should be killed
when she or he completely logs out (i.e. after
her/his last session ended). Defaults to
<literal>no</literal>.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>KillOnlyUsers=</varname></term>
<term><varname>KillExcludeUsers=</varname></term>
<listitem><para>These settings take
space separated lists of user names
that influence the effect of
<varname>KillUserProcesses=</varname>. If
not empty only processes of users
listed in
<varname>KillOnlyUsers</varname> will
be killed when they log out
entirely. Processes of users listed in
<varname>KillExcludeUsers=</varname>
are excluded from being
killed. <varname>KillExcludeUsers=</varname>
defaults to <literal>root</literal>
and takes precedence over
<varname>KillOnlyUsers=</varname>
which defaults to the empty list.</para></listitem>
</varlistentry>
<varlistentry>
<term><varname>Controllers=</varname></term>
<term><varname>ResetControllers=</varname></term>
<listitem><para>These settings control
the default control group hierarchies
users logging are added to. When
logging in users will get private
control groups in all hierarchies
listed in
<varname>Controllers=</varname> and be
reset to the root control group in all
hierarchies listed in
<varname>ResetControllers=</varname>. <varname>Controllers=</varname>
defaults to the empty list,
<varname>ResetControllers=</varname>
defaults to
<literal>cpu</literal>.</para></listitem>
</varlistentry>
</variablelist>
<para>Note that setting
<varname>KillUserProcesses=1</varname> will break tools
like
<citerefentry><refentrytitle>screen</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
<para>Note that <varname>KillUserProcesses=1</varname>
is a weaker version of
<varname>kill-session-processes=1</varname> which may
be configured per-service for
<citerefentry><refentrytitle>pam_systemd</refentrytitle><manvolnum>8</manvolnum></citerefentry>. The
latter kills processes of a session as soon as it
ends, the former kills processes as soon as the last
session of the user ends.</para>
