Yes, at the kernel level the long term plan is to eventually
get rid of vz-specific API and switch to namespaces/cgroups
completely. Thus any new users that sit on the vzkernel API
make this process ... harder :)

We will keep the CLI (vzctl) and library (libvzctl) working on
new OpenVZ installations for some time (several years, I suppose)
by making them properly redirect calls to new API.

But all the new features will be implemented within the new API,
libcontainer/PCS SDK.
