For myself, I'm using Debian (sid), no customizations; just the stock
distro kernel (and packages)

That's a useful tip; thanks.
In my case, it was working (very well) with the Debian kernel packages
from Jan 2012 - linux-image-3.2.0-1-amd64_3.2.1-1_amd64.deb seemed to
work just fine for me.
While I suspect something kernel-related (since it was a reboot that
changed my system from working fine to its current state), I'm just not
sure what the cause could be. Is this a kernel issue, or userspace?
The thing that blows my mind is that liblxc *vanishes entirely* from
the system's dynamic linker after I try to run lxc the first time.
As a follow up of other things I've tried:
* Creating a "new" lxc container: Won't start, same errors.
* Starting a previously "working" container at boot: Won't start; I
don't recall the error offhand, but I do know the container had no
issues before, and was shutdown properly.
Another note:
- Debian defaults to using /var/lib/lxc. Not wanting to go to the
trouble to change this, I did a bind mount in my fstab:
/srv/lxc /var/lib/lxc none bind 0 0
I don't see a reason the bind mount should cause a problem, but I
figure it's worth mentioning.
