And I tend to omit the slice at all. :-)

This is so easy because I very often use sysinstall for
initializing the disk when installing, but any further
disk adding is done via CLI as shown above, because it's
much simpler - and I didn't see any reason to create a
slice - even if I wanted to have more than one partition,
which I often don't want.

You say it: I KNEW that there was something someone had
on his mind when reserving 'd' for something special...
but WHAT it exactly was, I don't know.
