<title>Description</title>
<para><filename>systemd-getty-generator</filename> is
a generator that automatically instantiates
<filename>serial-getty@.service</filename> on the
kernel console <filename>/dev/console</filename> if
that is not directed to the virtual console
subsystem. It will also instantiate
<filename>serial-getty@.service</filename> instances
for virtualizer consoles, if execution in a
virtualized environment is detected. Finally, it will
instantiate
<filename>container-getty@.service</filename>
instances for additional container pseudo TTYs as
requested by the container manager (see <ulink
url="http://www.freedesktop.org/wiki/Software/systemd/ContainerInterface/"><filename>Container Interface</filename></ulink>). 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 <varname>console=</varname> to get
both kernel messages and a getty prompt on a serial
TTY. See <ulink
url="https://www.kernel.org/doc/Documentation/kernel-parameters.txt"><filename>kernel-parameters.txt</filename></ulink>
for more information on the
<varname>console=</varname> kernel parameter.</para>
<para><filename>systemd-getty-generator</filename>
implements the <ulink

specification</ulink>.</para>

gettys you may find in <ulink

Consoles (and Elsewhere)</ulink>.</para>
