systemd-getty-generator - Generator for enabling getty instances
on the console
/usr/lib/systemd/system-generators/systemd-getty-generator
systemd-getty-generator is a generator that automatically
instantiates [email protected] on the kernel consoles, if
they can function as ttys and are not provided by the virtual
console subsystem. It will also instantiate [email protected]
instances for virtualizer consoles, if execution in a virtualized
environment is detected. If execution in a container environment
is detected, it will instead enable console-getty.service for
/dev/console, and [email protected] instances for
additional container pseudo TTYs as requested by the container
manager (see Container Interface[1]). This should ensure that the
user is shown a login prompt at the right place, regardless of
which environment the system is started in. For example, it is
sufficient to redirect the kernel console with a kernel command
line argument such as console= to get both kernel messages and a
getty prompt on a serial TTY. See The kernel's command-line
parameters[2] for more information on the console= kernel
parameter.
systemd-getty-generator implements systemd.generator(7).
Further information about configuration of gettys can be found in
systemd for Administrators, Part XVI: Gettys on Serial Consoles
(and Elsewhere)[3].
systemd-getty-generator understands the following
kernel-command-line(7) parameters:
systemd.getty_auto=
this options take an optional boolean argument, and default
to yes. The generator is enabled by default, and a false
value may be used to disable it.
Added in version 250.
$SYSTEMD_GETTY_AUTO
This variable takes an optional boolean argument, and default
to yes. The generator is enabled by default, and a false
value may be used to disable it.
Added in version 250.
getty.ttys.serial, getty.ttys.container
These system credentials may be used to spawn additional
login prompts on selected TTYs. The two credentials should
contain a newline-separated list of TTY names to spawn
instances of [email protected] (in case of
getty.ttys.serial) and [email protected] (in case of
getty.ttys.container) on.
Added in version 254.
