In responding to a post on misc@, I noticed that bioctl(8) uses all sd(4) devices in the examples sections while softraid(4) uses wd(4) devices for the chunks. This patch updates softraid.4 to use sd(4) devices as well. I have not used a wd(4) device in years and I think it more confusing to use examples with wd(4) when almost everything these days is sd(4).
