From 0ee679580e55b4b7fe6c68bf63d953017c489617 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Mon, 22 Apr 2013 20:39:03 -0400 Subject: systemd: fall back to mounting /sys/fs/cgroup sans xattr xattrs on cgroup fs were added back in v3.6-rc3-3-g03b1cde. But we support kernels >= 2.6.39, and we should also support kernels compiled w/o xattr support, even if systemd is compiled with xattr support. Fall back to mounting without xattr support.
