When using ynh_systemd_action with the option --line_match= or -l, the package have to use also ynh_clean_check_starting into the ynh_clean_setup function.
Otherwise, if the script fails while ynh_systemd_action is running with --line_match=, it's going to hang forever because of tail (or journalctl) still running.
