autoinstallation - stops briefly with "zzz_reboot"

This document (000020337) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 SP3

Situation

final_reboot is set in the autoyast control file's mode section.

After the first reboot and some system configuration steps and auto-install settings were finished, a pop-up window with the below "Warning" appears on the screen:

#<Y2Autoinstallation::InitScript:0x000055e552eeda30 @filename="zzz_reboot", @source="shutdown -r now", @location="", @debug=true>
#<Y2Autoinstallation::InitScript:0x000055e552eed9b8 @filename="zzz_reboot", @source="shutdown -r now", @location="", @debug=true>

The pop-up also provides an OK and Stop button.
However without doing anything the window will close automatically after a few seconds and the autoinstallation continues and finishes successfully.

Resolution

The autoyast maintenance update (autoyast2-4.3.89-3.22.1) released September 2021 includes the patch to avoid the warning.

Workaround:

Instead of using the "final_reboot" element explicitly add a custom script for reboot, (basically the same which is added by the "final_reboot" option internally by YaST):

<scripts>
<init-scripts config:type="list">
    <script>
      <filename>zzzz_reboot</filename>
      <interpreter>shell</interpreter>
      <source><![CDATA[shutdown -r now ]]>
      </source>
    </script>
</init-scripts>
</scripts>

Cause

The code in the autoinst.ycp adds the script in the Import method unconditionally.
The first script is added when loading the XML in the initial installation, the second is added again when loading the data in the second stage.
