+# Set up device nodes and /servers translators.
+#
+# Use cases:
+#   - from d-i's /libexec/runsystem, to create a minimal set of device nodes
+#     and translators for the installer environment;
+#   - from debootstrap on initial installation, to create device and server
+#     nodes before /dev and /servers are firmlinked to the host system.
+#   - from hurd.postinst, on upgrade, where only non-existant nodes should be
+#     created, and the other ones should be left alone.
