BSD disklabel is limited to a maximum of 8 slices per MBR partition.  The
'c' slice is reserved for the entire disk which leaves you with 7 usable.
Not sure where the 6 number comes from unless you always block 'b' off for
swap, or perhaps Adrian was meaning the old rule in sysinstall that seemed
to only used the 'a' slice for the root partition.  Theoretically you could
probably end up with 28 slices (7 slices for each of 4 MBR partitions),
maybe more if you delve into the murky underworld of extended partitions.

"man disklabel" shows that the highest slice can be 'h', and I believe its
correct.
