Subject: [PATCH 35/37] DNFWorkaround: extend the model by script_args
The original model provided a possibility to execute a script
that will handle problems before the DNF / RPM transaction,
in correct contexts (overlay, host system, ..) before any use
of the upgrade dnf plugin.
But current solution provided only the script_path field, which
suggests it should contain only the path to the script. The executed
command (inside a context) looked like this:
bash -c script_path
However we have realized we need to be able to execute a script
with additional arguments. Regarding that, introducing
the script_args field. SO the final command looks like this:
bash -c 'script_path arg1 arg2..'
when script_args are specified. The default is set to an empty
list.
