Unfortunately another parse procedure in _gets_settings() is needed
to handle the command line option, since metadata_cache option in
lvm.conf is processed in init_lvm() before a command line option is
parsed in lvm_run_command().

But thank you for the suggestion. Command line '--config' option
should be handled as well. I will update this in the next version.

Thanks,
