From 992807de55bd9b0e8cbb569a86bb84b75fe9482e Mon Sep 17 00:00:00 2001 From: Alexander V Vershilov Date: Sun, 30 Jun 2013 16:32:30 +0400 Subject: [PATCH] Put a service on into a top hierarchy of each cgroup This change will fix unwanted cgroup inheriting from user cgroups, and fixes issues with systemd cgroup tracking by logind. However this fix can lead to incorrect work for some user cgroup controllers - so more advanced solution, that coveres such cases will be created later. Thanks to Fabio Erculiani (lxnay) for testing and general idea. --- sh/rc-cgroup.sh.in | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/sh/rc-cgroup.sh.in b/sh/rc-cgroup.sh.in index d96aa164..21f5f50d 100644 --- a/sh/rc-cgroup.sh.in +++ b/sh/rc-cgroup.sh.in @@ -72,6 +72,14 @@ cgroup_set_values() cgroup_set_limits() { + # relocate starting process to the top of the cgroup + # it prevents from unwanted inheriting of the user + # cgroups.
