(s) is just ugly with a vibe of DOS. In most cases just using the normal plural form is more natural and gramatically correct. There are some log_debug() statements left, and texts in foreign licenses or headers. Those are not touched on purpose.

<title>Description</title>
|
|
|
|
<para><filename>systemd-getty-generator</filename> is a generator that automatically instantiates
|
|
<filename>serial-getty@.service</filename> on the kernel consoles, if they can function as ttys and are
|
|
not provided by 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. If execution in a container environment is detected, it will instead
|
|
enable <filename>console-getty.service</filename> for <filename>/dev/console</filename>, and
|
|
<filename>container-getty@.service</filename> instances for additional container pseudo TTYs as requested
|
|
by the container manager (see <ulink url="https://systemd.io/CONTAINER_INTERFACE"><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://docs.kernel.org/admin-guide/kernel-parameters.html">The kernel's command-line
|
|
parameters</ulink> for more information on the <varname>console=</varname> kernel parameter.</para>
