It says "Max path length 4096". But we run into a similar error in
the coreutils test, it does look LXC related somehow.

It doesn't exist; bzr's debian/tests/control needs to pull that in as
a test dependency; or, if that's not test specific but bzr itself
needs it, then bzr needs to grow a dependency to it.

Right, there were a few failed runs with using aufs as overlay file
system, which caused this. So I disabled aufs again and now use
cloning on ppc64el; much slower, but avoids the various bugs that we
see with aufs and overlayfs there.

Correct, that's the problem. Look at the previous log at
https://jenkins.qa.ubuntu.com/job/trusty-adt-juju-core-ppc64el/6/console

Thanks,

Martin
