.SH "NAME"
systemd-getty-generator \- Generator for enabling getty instances on the console
.SH "SYNOPSIS"
.PP
/usr/lib/systemd/system\-generators/systemd\-getty\-generator
.SH "DESCRIPTION"
.PP
systemd\-getty\-generator
is a generator that automatically instantiates
serial\-getty@\&.service
on the kernel console
/dev/console
if that is not directed to the virtual console subsystem\&. It will also instantiate
serial\-getty@\&.service
instances for virtualizer consoles, if execution in a virtualized environment is detected\&. Finally, it will instantiate
container\-getty@\&.service
instances for additional container pseudo TTYs as requested by the container manager (see
\m[blue]\fBContainer Interface\fR\m[]\&\s-2\u[1]\d\s+2)\&. 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
\fIconsole=\fR
to get both kernel messages and a getty prompt on a serial TTY\&. See
\m[blue]\fBkernel\-parameters\&.txt\fR\m[]\&\s-2\u[2]\d\s+2
for more information on the
\fIconsole=\fR
kernel parameter\&.
.PP
systemd\-getty\-generator
implements the
\m[blue]\fBgenerator specification\fR\m[]\&\s-2\u[3]\d\s+2\&.
.PP
Further information about configuration of gettys you may find in
\m[blue]\fBsystemd for Administrators, Part XVI: Gettys on Serial Consoles (and Elsewhere)\fR\m[]\&\s-2\u[4]\d\s+2\&.
