Kernel developer proposes making containers a kernel object via "cells"

Josef Bacik has proposed a concept called "cells" to turn containers into a first-class kernel object in Linux. The kernel currently has no container abstraction, assembling it from namespaces, cgroups and sandboxing mechanisms; earlier attempts never got far.

• The Linux kernel does not recognize containers as a distinct object
• Containers are assembled from namespaces, cgroups and sandboxes
• Josef Bacik proposed a concept called "cells"
• Previous attempts to make containers a kernel object failed
