One does not need systemd in order to have control groups. Control groups are a kernel mechanism. However note that the headlined software needs version 2 of Linux control groups.
- LinuxBender 8y agoAgreed. I tried to use it on centos 6 but it was very incomplete. The kernel is just too old. I started using kernels from elrepo to work around this, but not many will do that in a production environment.
- mdaniel 8y ago> The kernel is just too old For my curiosity, is there a technical reason for the distro to use an old kernel? I would think one would wish to have all the bug fixes available, and I don't think the kernel has a bad backward compatibility story, so from the outside it seems like a sure thing -- leading me to believe there must be more to the story.
- LinuxBender 8y agoEnterprise distros such as Redhat fork the kernel, then patch for bugs and vulnerabilities, to avoid adding too many new features to a major version release of the OS. This actually makes a lot of sense from a stability and predictability perspective. It would be significantly harder to support the upstream kernel releases, as new features and behavioral changes occur rather often.
