79 | <listitem><para>Takes a positive integer. Configures how many | |
80 | virtual terminals (VTs) to allocate by default that, when | |
81 | switched to and are previously unused, | |
82 | <literal>autovt</literal> services are automatically spawned | |
83 | on. These services are instantiated from the template unit | |
84 | <filename>autovt@.service</filename> for the respective VT TTY | |
85 | name, for example, <filename>autovt@tty4.service</filename>. | |
86 | By default, <filename>autovt@.service</filename> is linked to | |
87 | <filename>getty@.service</filename>. In other words, login | |
88 | prompts are started dynamically as the user switches to unused | |
89 | virtual terminals. Hence, this parameter controls how many | |
90 | login <literal>gettys</literal> are available on the VTs. If a | |
91 | VT is already used by some other subsystem (for example, a | |
92 | graphical login), this kind of activation will not be | |
93 | attempted. Note that the VT configured in | |
94 | <varname>ReserveVT=</varname> is always subject to this kind | |
95 | of activation, even if it is not one of the VTs configured | |
96 | with the <varname>NAutoVTs=</varname> directive. Defaults to | |
97 | 6. When set to 0, automatic spawning of | |
98 | <literal>autovt</literal> services is | |
99 | disabled.</para></listitem> | |

105 | <listitem><para>Takes a positive integer. Identifies one | |

108 | The VT selected with this option will be marked busy | |
109 | unconditionally, so that no other subsystem will allocate it. | |
110 | This functionality is useful to ensure that, regardless of how | |
111 | many VTs are allocated by other subsystems, one login | |
112 | <literal>getty</literal> is always available. Defaults to 6 | |
113 | (in other words, there will always be a | |
