This improves compatibility of xenial containers running on unified cgroup hierarchy hosts. [Test Case] * Xenial containers should boot, with non-writable unified cgroup hierarchy hosts. [Regression Potential] * unified cgroup hierarchy is not in use by default on xenial hosts, thus this is forward compatibility improvment with e.g. bionic hosts running xenial containers. [Other Info] * Original bug report Hey everyone, Current systemd versions all fail when the unified cgroup hierarchy is not-writable. This is especially problematic in containers where the systemd administrator might decide to not delegate the unified hierarchy or when running with a liblxc driver that doesn't yet know how to handle the unified cgroup hierarchy. I've pushed patches to systemd upstream that let systemd ingnore the non-delegated unified hierarchy. The relevant commits are: e07aefbd675b651f8d45b5fb458f2747b04d6e04 2d56b80a1855836abf1d7458394c345ad9d55382 1ff654e28b7b8e7d0a0be33522a84069ac6b07c0 These patches will be in 236 but should be backported from xenial upwards.
