[Lxc-users] Contents of container deleted during maintenance -- What went wrong??

I'm an experienced Debian and GNU/Linux user. Last night I was trying to 
get my "torrent" container working after the upgrade to Debian Wheezy. 
The contents of /lxc/torrent, which contained the directory hierarchy of 
the "torrent" container with the help of AUFS, were deleted at some 
point during the proceedings, and I can't figure out why. Is it possible 
`lxc-destroy -n torrent' or `lxc-execute -n torrent' could have caused 
these files to be deleted? Is a catastrophic malfunction of AUFS a 
possibility? I *definitely* never called `rm', particularly not with any 
wildcards.

I never plan to do this complicated AUFS setup again for a container, 
but to summarize:
/lxc/base - hierarchy common to all containers
/lxc/torrent_rw - differences between /lxc/torrent and /lxc/base are 
stored here
/lxc/torrent - root of container "torrent"'s hierarchy (contents 
mysteriously deleted)

The system is 3.2.0-4-kirkwood #1 Debian 3.2.46-1

A transcript of my entire session is attached. I have clearly noted 
where I "snipped" output from the file, but nothing relevant has been 
changed.
