Actually, with the new xbf(4) we don't need it on Xen anymore (;

I did not know that. I've only used OpenBSD under VMware products and
bhyve. That makes sense.

wd(4) is still alive. For example, we use it on VMs where we don't have a PV 
disk driver yet (Xen, Hyper-V).

I did notice that too. I can understand that point of view. If that is
preferred, it is fine by me.

morning.

i kind of disagree: i don;t think it does any harm to show these examples
using wd. if anything, it might force the reader to think about what
they're doing.

note also that the final example in bioctl(8) has an example using a
chunk on a wd disk.

[PATCH] softraid.4 move wd(4) examples to sd(4)

2016-12-05 Thread Bryan Vyhmeister 
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).
