+Security note
+-------------
+
+It should be noted that a privileged process inside jchroot may be
+able to escape unless its privileges are reduced. For example, it
+could fiddle with `/dev/kmem` or mount any filesystem after creating
+the appropriate node.
+
+If you seek a complex isolation, you are better off with [lxc][2]
+which bundles many security mechanisms.
