Developers of the above software can opt into the unified hierarchy with "systemd.legacy_systemd_cgroup_controller=0". --- src/basic/cgroup-util.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/basic/cgroup-util.c b/src/basic/cgroup-util.c index 5e73753..dc13025 100644 --- a/src/basic/cgroup-util.c +++ b/src/basic/cgroup-util.c @@ -2423,10 +2423,10 @@ bool cg_is_unified_systemd_controller_wanted(void) { r = get_proc_cmdline_key("systemd.legacy_systemd_cgroup_controller=", &value); if (r < 0) - return true; + return false; if (r == 0) - wanted = true; + wanted = false; else wanted = parse_boolean(value) <= 0; } -- 2.10.1
