The user namespace, which is a important piece of Linux containers, has been merged into the mainline of the kernel since 3.8. However, it implementation is still incomplete for some components of the kernel. Hence, to enable the feature we need to disable some features: network filesystems and XFS.

| * This release removes high-level support for the | |
| MemorySoftLimit= cgroup setting. The underlying kernel | |
| cgroup attribute memory.soft_limit= is currently badly | |
| designed and likely to be removed from the kernel API in its | |
| current form, hence we shouldn't expose it for now. | |
| * The memory.use_hierarchy cgroup attribute is now enabled for | |
| all cgroups systemd creates in the memory cgroup |
