[Bug 1507463] Re: OverlayFS: Wrong mnt_id and path reported in /proc in linux-3.13

[Chris J Arges]

I tried the following:

# Install the 3.13 kernel and also an affected version of lxc.
lxc-create -t download -n trusty -- -d ubuntu -r trusty -a amd64;
touch $HOME/test.txt;
echo "lxc.mount.entry = $HOME/test.txt home/ubuntu/test.txt none bind,create=file 0 0" >> $HOME/.local/share/lxc/trusty/config;
lxc-clone -s -B overlayfs trusty trusty_overlay;
lxc-start -n trusty_overlay; # fails to start

In a clean and fully updated Trusty VM and could not reproduce the issue with the trusty version of the packages. 
ii  lxc                              1.0.7-0ubuntu0.7                 amd64        Linux Containers userspace tools

I also tried the stable version of LXC (https://launchpad.net/~ubuntu-lxc/+archive/ubuntu/lxc-stable) and was able to get this working.
ii  lxc                              1.1.4-0ubuntu1~ubuntu14.04.1~ppa1 amd64        Linux Containers userspace tools

So seems to be fixed in 1.1.4, and I suspect this commit fixes the issue:

    overlayfs_mount: create delta dir if it doesn't exist


Can you re-test with 1.1.4 and see if that fixes the issue? Thanks,
