machine and container virtualization are used in
conjunction, only the latter will be identified (unless
<option>--vm</option> is passed).</para>
+ <para> Windows Subsystem for Linux is not a Linux container,
+ but an environment for running Linux userspace applications on
+ top of the Windows kernel using a Linux-compatible interface.
+ WSL is categorized as a container for practical purposes.
+ Multiple WSL environments share the same kernel and services
+ should generally behave like when being run in a container.</para>
