From:
http://en.wikipedia.org/wiki/Lxc
LXC is similar to other OS-level virtualization technologies on Linux
such as OpenVZ <http://en.wikipedia.org/wiki/OpenVZ> and Linux-VServer
<http://en.wikipedia.org/wiki/Linux-VServer>, as well as those on other
operating systems such as FreeBSD jails
<http://en.wikipedia.org/wiki/FreeBSD_jail>, AIX
<http://en.wikipedia.org/wiki/AIX> Workload Partitions
<http://en.wikipedia.org/wiki/Workload_Partitions> and Solaris
Containers <http://en.wikipedia.org/wiki/Solaris_Containers>. In
contrast to OpenVZ, LXC works in the vanilla Linux kernel
<http://en.wikipedia.org/wiki/Vanilla_Linux_kernel> requiring no
additional patches to be applied to the kernel sources. Version 1 of the
LXC, which was released on 20 February 2014, is a long-term supported
version and intended to be supported for five years.^[6]

The above -- if it works and does not require "excessive" system
resources would be the solution we need, as it has something akin to
real polymorphism. Does it have something akin to inheritance, using
all of the base (native) environment except as needed to avoid
inconsistencies? Can one load, say, the appropriate glibc within a LXC
container without loading what is tantamount to a full OS environment?
Any comments from actual users of LXC or any competitors/alternatives
thereto?\
I am in the field today, and in a time constrained situation, and thus
no time to hunt -- are any of these available via RPMs in a production
release with some sort of built-in configuration tool(s)?
