dump(8) tends to generate the name of a raw device by inserting an 'r'
after the last '/' of the device name. We should get rid of this
conversion soon.


Bob> So how do you dump a vinum filesystem?

You can create a link to the node of a vinum volume, named 'r(volume
name)'. eg

cd /dev/vinum ; ln faithful rfaithful
