Comment 19 for bug 1410876

I think the failed to allocate pty bit is a red herring - it looks like the original failure is this:

error executing "lxc-clone": lxc_container: utils.c: mkdir_p: 220 Not a directory - failed to create directory '/run/lock/lxc//var/lib/lxc/juju-trusty-lxc-template/snaps';

This error comes from lxc's use of libc's mkdir(), which is setting errno to ENOTDIR, meaning one of the components in the directory it's trying to create is not actually a directory.

So, which part of the '/run/lock/lxc//var/lib/lxc/juju-trusty-lxc-template/snaps' path might exist as a non directory?
