| 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 |
