AdNsi is, IIRC, an old (compatibility) scheme. I am not quite sure how=20 it works when you have more than one slice on the same disk (e.g.=20 ad0s1a, ad0s1e, ad0s1f; ad0s2a, ad0s2e, ad0s2f ...); on the other=20 hand, I use the ordinary label(l)ing in my /etc/fstab. AFAICS, some people don't like the different schemes (0 =3D initial=20 disk; 1 initial slices); but that's another matter.
