Chris,

Oh, duh, of course: the a & d are partition labels just like they with wd0a,d 
etc.
Sorry, I was being dense.

I used /dev/rvnd0d because when I ran "vnconfig vnd0 ...." with the -v (verbose)
option, it gave me the message:-

"/dev/rvnd0d: 615491584 bytes on i386pkg2.iso"

so I assumed that was what I was supposed to use in the mount command.

Why do you suppose it did that?

b.t.w. I come from Hounslow, suburb of London, and spent my teen years in
Cheltenham before moving to the states for my employer in '82. Been away
waaaaay too long!

julian.
