Recent systemd changes for cgroups and namespaces.
View systemd-changelogs.txt
systemd 208 released [LWN.net] http://lwn.net/Articles/569235/
* 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
