Adding linux tasks. This overlayfs change might be due to its upstreamization, or unintended, so please invalidate if appropriate. Thanks!

Status in linux package in Ubuntu: Incomplete Status in lxc package in Ubuntu: New Bug description: With the previous vivid kernel 3.16.0-28-generic,"lxc-start-ephemeral -o containername" works fine. With the current 3.18.0-8-generic it fails with "the container failed to start". This is reproducible in a clean cloud VM: $ sudo apt install lxc $ sudo lxc-create -t busybox -n c1 # works fine under all kernels: $ sudo lxc-start -n c1 -F $ sudo lxc-start-ephemeral -o c1 The container 'c1-0twqb553' failed to start. It happens with both the above busybox as well as with a full ubuntu OS container, so I don't think that's relevant. Unfortunately lxc-start-ephemeral has no --logfile or --logpriority or similar debugging tools, and even with -k it doesn't keep a container or logs around for inspection. dmesg might have something worth noting, look at the third line: [ 465.694541] device vethQLD78J entered promiscuous mode [ 465.694611] IPv6: ADDRCONF(NETDEV_UP): vethQLD78J: link is not ready [ 465.726758] overlayfs: missing upperdir or lowerdir or workdir [ 465.744501] eth0: renamed from vethWRSY7B [ 465.745673] IPv6: ADDRCONF(NETDEV_CHANGE): vethQLD78J: link becomes ready [ 465.745693] lxcbr0: port 1(vethQLD78J) entered forwarding state [ 465.745697] lxcbr0: port 1(vethQLD78J) entered forwarding state [ 465.746618] lxcbr0: port 1(vethQLD78J) entered disabled state [ 465.747134] device vethQLD78J left promiscuous mode [ 465.747140] lxcbr0: port 1(vethQLD78J) entered disabled state So maybe overlayfs changed its semantics somehow in the new kernel?
