-Linux Containers, or LXC, is operating system-level method for running multiple separate isolated Linux installations (containers) on a single host. Rather than simulating the computer hardware as in true virtualization, LXC uses the cgroups and namespaces functionality of the host's Linux kernel to provide strong isolation of the container. It is an intermediate solution between chroots and full virtualization, having a small impact on system resource usage similar to chroots, but providing better isolation. They provide a very convenient way to, among other things, maintain a clean build environment or test software against different [Linux] OS versions.+Linux Containers, or LXC, is operating system-level method for running multiple separate isolated Linux installations (containers) on a single host.

-The name of the bridge, gateway, netmask, and many other parameters can be modified in /etc/default/lxc/lxc-net. For a complete list, simply open up /usr/libexec/lxc/lxc-net in your favorite editor or pager; there is a comment indicating which variables can be changed.+The name of the bridge, gateway, netmask, and many other parameters can be modified by setting the proper variables in /etc/default/lxc/lxc-net. For a complete list, simply open up /usr/libexec/lxc/lxc-net in your favorite editor or pager; there is a comment indicating which variables can be changed. Set them in /etc/default/lxc/lxc-net rather than modifying /usr/libexec/lxc/lxc-net directly.
  
 To actually use this network within the container, there are a few steps that will need to be taken during the initial creation and setup of the container, which will be covered in the next section. To actually use this network within the container, there are a few steps that will need to be taken during the initial creation and setup of the container, which will be covered in the next section.
