+# This file gives iostat and sadc a clue about how to find whole
+# disk devices in /proc/partitions and /proc/diskstats
+# Authoritative source is: linux/Documentation/devices.txt
+#
+# line format, general record:
+# major:name:ctrlpre:ctrlno:devfmt:devcnt:partpre:partcnt:description
+#
+# major: major # for device
+# name: base of device name
+# ctrlpre: string to use in generating controller designators
+# eg: the c in c0d2p6, decimal formatting implied
+# '*' means none or irrelevant
+# 'x': exception... record contains a specific name
+# for a specific minor #, stored in the ctrlno field
+# ctrlno: which controller of this type is this
+# devfmt: type of device naming convention
+# a: alpha: xxa, xxb, ... xxaa, xxab, ... xxzz
+# %string: string to use in generating drive designators,
+# eg: the 'd' in c0d2p6 , decimal formatting implied
+# d: no special translations (decimal formatting)
+# devcnt: how many whole devs per major number
+# partpre: appended to whole dev before part designator
+# eg. the p in c0d2p6, decimal formatting implied
+# '*' means none
+# partcnt: number of partitions per volume
+# or minor # for exception records
+# description: informative text
+#
+# line format, indirect record:
+# major:base_major:ctrlno[:[desc]]
+#
+# major: major number of the device
+# base_major: major number of the template for this type,
+# 0 for not supported
+# ctrlno: controller number of this type
+# desc: controller-specific description
+# if absent the desc from base_major will be
+# used in sprintf( buf, desc, ctrlno )
