I see there are several rumored sources of restrictions on hardlinks, e.g.
https://lkml.org/lkml/2011/5/19/384
https://lkml.org/lkml/2012/2/21/397

And I see this is a known issue:
http://comments.gmane.org/gmane.linux.ubuntu.devel/34948

Happily, using the -U aufs option to lxc-start-ephemeral seems to work
around the problem, at least in my little test.  I'll know soon if it fixes
my real system.

But I was not able to find a bug for this issue in launchpad.  Should
I file one?
