From 419fd7449fe1a984f582731fcd4d9455000846b0 Mon Sep 17 00:00:00 2001
From: Alexander Morozov <lk4d4@docker.com>
Date: Wed, 4 Nov 2015 13:51:46 -0800
Subject: [PATCH] Use fs cgroups by default
Our implementation of systemd cgroups is mixture of systemd api and
plain filesystem api. It's hard to keep it up to date with systemd and
it already contains some nasty bugs with new versions. Ideally it should
be replaced with some daemon flag which will allow to set parent systemd
slice.

The `native.cgroupdriver` option specifies the management of the container's
cgroups. You can specify `cgroupfs` or `systemd`. If you specify `systemd` and
-it is not available, the system uses `cgroupfs`. By default, if no option is
-specified, the execdriver first tries `systemd` and falls back to `cgroupfs`.

+This example sets the `cgroupdriver` to `systemd`:
- $ sudo docker daemon --exec-opt native.cgroupdriver=cgroupfs
+ $ sudo docker daemon --exec-opt native.cgroupdriver=systemd
Setting this option applies to all containers the daemon launches.
