Comment 0 for bug 1734410

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:

1ff654e28b7b8e7d0a0be33522a84069ac6b07c0

These patches will be in 235 but should be backported from xenial upwards.
