Subject: [bug#68392] [PATCH v2] scripts: pack: Set correct default value for entry-point-argument.

From: Tomas Volf <[email-masked]>
Date: Fri, 12 Jan 2024 00:45:34 +0100

The default value of #f led to ("..." . #f) being passed further down as an
entry point.  That is not an issue for command line invocation, since in that
code path '() was already used as a default value, but it broke docker system
test with the following error:
