+Here is an example of what the partition information will look like once
+you have entered the disklabel editor. Disk partition sizes and offsets
+are in sector (most likely 512 bytes) units. Make sure these size/offset
+pairs are on cylinder boundaries (the number of sector per cylinder is
+given in the `sectors/cylinder' entry, which is not shown here).
+
+Do not change any parameters except the partition layout and the label name.
+It's probably also wisest not to touch the `8 partitions:' line, even
+in case you have defined less than eight partitions.
+
+[Example]
+8 partitions:
+#        size   offset    fstype   [fsize bsize   cpg]
+  a:    50176        0    4.2BSD     1024  8192    16   # (Cyl.    0 - 111)
+  b:    64512    50176      swap                        # (Cyl.  112 - 255)
+  c:   640192        0   unknown                        # (Cyl.    0 - 1428)
