Not really. I met this problem when I was using lvcreate with the --wipesignature option. 
--yes works for me. But I also found that --force should also work when I read the source.
However, it reports -f/--force is an invalid option for lvcreate.

Currently there is no introduction to --yes in the manpage of lvcreate. How about adding it to
the manpage?
