I don't understand this sentence:

     -A      This option causes swapctl to read the /etc/fstab file for
             devices and files with a ``sw'' and ``dp'' type, and adds all
             these entries as swap devices, or for a dump device in the case
             of a ``dp'' type.

The bit "or for a dump device..." is redundant? or am I missing something?

Cheers,

Patrick
