Bug#779473: Bug #779473: lxc-attach: internal error connecting to container

[Christian Seiler]

Note that this is not necessarily only #777601, there's also #777164.
The fix in systemd 215-12 fixes part of the problem, but the other
part still persists.

I have posted a backported patch to #777164 for this issue (it's
fixed in 219 upstream).

(I'm leaving this closed since it's already tracked in the other bug.
But if somebody has the same issue with lxc-attach, they should know
where to look, that's why I'm replying here.)
