Thank you for your bug report. However I am not sure what exactly
you are asking for. If its a new feature you are asking for, or a
design change, please discuss it on the upstream mailing list:
E-MAIL: util-li...@vger.kernel.org
URL: http://vger.kernel.org/vger-lists.html#util-linux
ARCHIVE: https://lore.kernel.org/util-linux/
I imagine upstream or other upstream contributors will have ideas
then.
Please reply with a link to the upstream discussion once this has
been discussed.
Thanks,
Chris
