Of course you're correct: bsdlabel shows "a:". In terminology, when
refering to a partition, it's usually said "partition a" or "partition
ad6s1a" instead of "partition a:". The convention "a:" - "drive letters" -
is very common in DOS, as well as in other "modern" MICROS~1 products. 
In fact, I was just joking, as when people are asking questions
about a "/home folder" or "hard discs". Terminology. :-)

As Wojciech mentioned, the *need* to have a slice on a disk is
mostly not there when you're using BSD only - there's no problem
if you don't have a slice, but just one partition covering the
whole disk. Then you just operate on this partition.

You can even newfs the whole disk without making a partition.
In this case, the c partition - "the whole disk" - is used,
and you can omit the c. If you newfs ad6, you end up with a
formatted ad6 partition ad6c, which is equivalent to ad6.
But that's going off-topic.
