Comment 6 for bug 1619285

I'm going to fix this in cloud-utils (growpart) in the way that we'd addressed this issue in the past:
 scraping text output of the command ran with LANG=C.

Not the best fix in the world.

What happened that caused this was that this commit is in 2.28.1:
  https://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/?id=e0d30ef4c

and then is subsequently reverted in trunk at
  https://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/?id=78e7f78896f2

I've sent a mail to upstream development list (Subject: request for sfdisk --no-blkrrpart) asking for a flag to tell sfdisk not to call blkrrpart, and then in the future we would just use that.
