Yes. The dumpdev is usually set to be the swap
'partition'. The word 'slice' describes one of the
areas of a hard disk which is specified in the DOS
'partition table'. This ambiguity is disgusting,
In BSD-land, the partitions are defined only in the
BSD disklabel, where each BSD 'partition' bears a
letter [a-z], and the swap 'partition' by long
tradition is named 'b'.
For example, on my DragonFly machine:
# disklabel ad1s6 [my DF 'slice']
<snip irrelevant junk>
# size offset fstype [fsize bsize bps/cpg]
a: 15739286 1048576 4.2BSD 2048 16384 89 # (Cyl. 65*- 1044*)
b: 1048576 0 swap # (Cyl. 0 - 65*)
c: 16787862 0 unused 0 0 # (Cyl. 0 - 1044*)
Thus, my DF swap 'partition' is named /dev/ad1s6b and the 'root' partition
is named /dev/ad1s6a.
The 'slice' ad1s6 is the second 'extended DOS partition' in the
'DOS Partition Table' which resides in sector 0 of the second physical
hard disk (/dev/ad1).
