 Ah, the wonders of being on the bleeding edge and looking for
guidance before anyone else has had the problem :)

 Arch also suffered this and one of their devs fixed it:
http://marc.info/?l=util-linux-ng&m=137945227914961&w=2

 That commit is in util-linux-2.24, which works for me.  I'm not sure
if the problem also applied to 2.23.1 (I don't have any systems
using that), but 2.23 was OK.

ĸen, currently upgrading all my 7.4-and-newer systems.
