| Subject: [PATCH] core: don't use the unified hierarchy for the systemd cgroup |
| yet (#4628) |
| |
| Too many things don't get along with the unified hierarchy yet: |
| |
| * https://github.com/opencontainers/runc/issues/1175 |
| * https://github.com/docker/docker/issues/28109 |
| * https://github.com/lxc/lxc/issues/1280 |
| |
| So revert the default to the legacy hierarchy for now. Developers of the above |
| software can opt into the unified hierarchy with |
| "systemd.legacy_systemd_cgroup_controller=0". |
