+# Udev rules for device-mapper devices.
+#
+# These rules create a DM control node in /dev/mapper directory.
+# The rules also create nodes named dm-x (x is a number) in /dev
+# directory and symlinks to these nodes with names given by
+# the actual DM names. Some udev environment variables are set
+# for use in later rules:
+#   DM_NAME - actual DM device's name
+#   DM_UUID - UUID set for DM device (blank if not specified)
+#   DM_SUSPENDED - suspended state of DM device (0 or 1)
+#   DM_UDEV_RULES_VSN - DM udev rules version
+#
+# These rules cover only basic device-mapper functionality in udev.
+#
+# Various DM subsystems may contain further subsystem-specific rules
+# in 11-dm-<subsystem_name>.rules which should be installed together
+# with the DM subsystem and which extend these basic rules.
+# For example:
+#   11-dm-lvm.rules for LVM subsystem
+#   11-dm-mpath.rules for multipath subsystem (since version 0.6.0, recommended!)
+#
+# Even more specific rules may be required by subsystems so always
+# check subsystem's upstream repository for recent set of rules.
+# Also, keep in mind that recent rules may also require recent
+# subsystem-specific binaries.
