These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.

<title>Description</title>
|
|
|
|
<para><filename>systemd-getty-generator</filename> is a generator
|
|
that automatically instantiates
|
|
<filename>serial-getty@.service</filename> on the kernel
|
|
console(s), 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://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/admin-guide/kernel-parameters.txt"><filename>kernel-parameters.txt</filename></ulink>
|
|
for more information on the <varname>console=</varname> kernel
|
|
parameter.</para>
