[yast-devel] Is there a way to turn off/ reduce output in autoyast?
Yast Developers, My customer has setup an autoyast installation (sles10 sp1) and it works great. The problem is log messages are output to the physical console AND over SOL (Serial Over LAN). This SOL connection is 9600 baud (please don't ask me to tell them to increase--they can't) so the installation can take quite a while because of all the text yast is spewing over this 9600 connection can take some time. They are asking if there's a way to reduce it or eliminate it?

Stefan, Customer is asking question with respect to the display, not the log file. So during installation, the rpms are filying by in the little dialog window with progress bar. Is there a way to limit that output? Or even the display period? -robert -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

Ah, you mean the output to that NCurses window that displays the package name
and description as each one is installed, not the log. Sorry, I had
misunderstood that.
AFAICS, the only way to suppress that output would be to patch some YCP code ,
and I don't think this is an option for an end user. Even worse, the relevant
code is all in YCP modules which are byte-compiled on the installation media,
so that byte code would have to be regenerated after patching the YCP code. I
don't think this can realistically be done.
But is that output really a performance bottleneck? Or is it more a "gut
feeling" that this customer has?
The NCurses library is really efficient at that: For every screen operation,
it sends only the difference between the old screen content and the new
screen content to the terminal (plus escape sequences to position the cursor
etc.).

Thinking that through once more, why not simply use a ssh installation if LAN
is available? Serial over LAN at 9600 baud strikes me as a very odd solution.

Hi, Maybe if it comes to "initializing the sources..." - downloading several files withs lots of Progress screens - then it sends quite of lot of screen changes per second. Maybe I'm wrong but this is my feeling from how I understand Roberto's question.

LAN install is not an option. This is a product that uses SLES. The SOL connection is needed because it connects to a management node and all nodes are controlled by the management node. -robert -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org
