Subject: [PATCH] tools,install-script: Add --config-file (-f) option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Let's add a new option so users can set their config from a file,
instead of directly passing the values via command-line.
CVE-2019-13313
Libosinfo: osinfo-install-script option leaks password via command line
argument. 'osinfo-install-script' is used to generate a script for
automated guest installations. It accepts user and admin passwords via
command line arguments, thus leaking them via process listing.
