NAME

6       systemd-getty-generator - Generator for enabling getty instances on the
7       console
8

SYNOPSIS

10       /usr/lib/systemd/system-generators/systemd-getty-generator
11

DESCRIPTION

13       systemd-getty-generator is a generator that automatically instantiates
14       serial-getty@.service on the kernel console(s), if they can function as
15       ttys and are not provided by the virtual console subsystem. It will
16       also instantiate serial-getty@.service instances for virtualizer
17       consoles, if execution in a virtualized environment is detected. If
18       execution in a container environment is detected, it will instead
19       enable console-getty.service for /dev/console, and
20       container-getty@.service instances for additional container pseudo TTYs
21       as requested by the container manager (see Container Interface[1]).
22       This should ensure that the user is shown a login prompt at the right
23       place, regardless of which environment the system is started in. For
24       example, it is sufficient to redirect the kernel console with a kernel
25       command line argument such as console= to get both kernel messages and
26       a getty prompt on a serial TTY. See kernel-parameters.txt[2] for more
27       information on the console= kernel parameter.
28
29       systemd-getty-generator implements systemd.generator(7).

31       Further information about configuration of gettys can be found in
32       systemd for Administrators, Part XVI: Gettys on Serial Consoles (and
33       Elsewhere)[3].

KERNEL COMMAND LINE

36       systemd-getty-generator understands the following kernel-command-
37       line(7) parameters:
38
39       systemd.getty_auto=
40           this options take an optional boolean argument, and default to yes.
41           The generator is enabled by default, and a false value may be used
42           to disable it.
43

ENVIRONMENT

45       $SYSTEMD_GETTY_AUTO
46           This variable takes an optional boolean argument, and default to
47           yes. The generator is enabled by default, and a false value may be
48           used to disable it.
