[Bug 941968] Re: lockfile-create hangs inside lxc containers (potential buffer overflow?)
@Sebastian, what you are seeing is likely unrelated to this particular bug. However if I simply do something like: juju deploy --repository=~/myrepo local:precise/ovs-lxc lxc-5678901234567890123456789012345678901 and very quickly juju debug-log then I see: LXCError: lxc-start: node name '' is too long lxc-start: failed to read configuration file Traceback (most recent call last): Could you confirm whether that is what you also see?

Sure. First, I ssh'd to project64198@deneb, a (metal) server of mine.

Simply running lockfile-create, killing it quickly, and re-running it in a container doesn't reproduce it for me. Can you please tell me which juju charm to use to reproduce this?
