%s [target_file_not_specified]

Error message

%s [target_file_not_specified]

What it means

Config guard in ldpreload Scan: the persistence target file (config.PersistenceTargetFile) is empty, so the plugin has no .so path to install into /etc/ld.so.preload. The plugin returns a failed Result with the i18n sentinel message rather than a Go error chain; the output buffer also prints persistence_file_required.
