Bug Description
In 3.13.0-33-generic, root in a non-init user namespace can do overlayfs mounts. In 3.16.0-5-generic he cannot.
Test case:
sudo apt-get install lxc
lxc-usernsexec -- /bin/bash # start a containerized root shell
# mkdir /tmp/a /tmp/b /tmp/c
# mount -t overlayfs -o upperdir=
This works in trusty, but not in latest utopic.
(A testcase for this will be added to the lxc-tests package, but isn't there yet)
