When no tty number is specified in the command line, let the tty service to provide choose one available tty and provide this one. The documentation is updated wrt this modification and I did a little fix to generate the date of the documentation. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com>

<para>
|
|
If the tty service has been configured and is available for the
|
|
container specified as parameter, this command will launch a
|
|
console allowing to log on the container.
|
|
</para>
|
|
|
|
<para>
|
|
The available tty are free slots taken by this command. That
|
|
means if the container has four ttys available and the command
|
|
has been launched four times taking the different tty, the fifth
|
|
command will fail because no console will be available.
|
|
</para>
|
|
|
|
<para>
|
|
The command will connect to a tty. If the connection is lost or
|
|
broken, the command can be launched again and regain the tty at
|
|
the state it was before the disconnection.
