Since the original patch I suggesting using --yes is not backward
compatible, I also suggested using `yes | lvcreate ...`, but that still
seems risky.

Other commenter in that bug thread above suggesting using
`--wipesignatures n`, but that's not backward compatible either, since I
think that option was introduced around the same time as `--yes`.

Another option would be to pipe `yes n` to lvcreate, which for the EXACT
bug about wiping (swap) would still result in creating the lv, but
(presumably) be safer, albeit with a warning message (probably good
thing anyway).

Regardless, either `yes | lvcreate ...` or `yes n | lvcreate` would get
around the issue I discovered on jessie, but still work for wheezy.
