Linux namespace container (LXC, Docker, containers) support
Linux namespace containers are increasingly being used to provide lightweight virtualisation, as in products like LXC, Docker's 'libcontainer' and our own 'containers':
User namespaces have been an official part of the Linux kernel for some time and have been considered feature-complete since the 3.8 release (we're at 3.14 right now).
There is a current feature request for Docker, and at least one older mention of LXC already on your system, both of which this request would cover:
As noted in the above request for Docker support, Red Hat and Openstack have both LXC and Docker support in the roadmap:
Since the above (two-year old) request, LXC has matured significantly and passed its 1.0 release. Docker is also approaching 1.0, and containers are at 1.2.
If cPanel could provide official support for this mainline kernel feature, it would open up a lot of new platforms for customers to run your products under the existing 'VPS' licence.
