 A container's file system activity is restricted to `/var/lib/lxc/<container-name>/rootfs`. When a container is destroyed all of `/var/lib/lxc/<container-name>` is also destroyed. You may have multiple containers and would like to share some file system space between them. You may have disposable containers and would like some file system space to outlive the container. In cases like these, you can create a host volume outside the container's `rootfs` and then mount that volume inside the container.

-Create the container mount point.
+To mount the volume inside the container there are two options.
+
+The first option requires two steps: manually create the mount target inside the container and then configure the container mount.
 
     root@host:~# lxc-attach --name mycontainer -- mkdir -p /container/mount/point
 
-Stop the container so that we can reconfigure it with the volume mount.

-    root@host:~# lxc-stop --name mycontainer
+The second option requires only one step: use `create=dir` when configuring the mount so that the mount target is automatically created inside the container for you.
 
-Add the volume mount to the container's configuration. (Note that the container mount point path is relative. It does not have a leading `/` character.)
