| <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> |
| <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> |

| <para>Note that setting |
| <varname>KillUserProcesses=1</varname> will break tools |

| |
| <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> |
