I wouldn't worry too much about it, just copy one of the existing entries
and adjust the main partition, or forget disktab and put it straight into
the disklabel. The scsi drives all id themselves at boot and tell you how
big they are. The sectors/track varies between cylinders on modern drives,
and this renders the tracks/cylinder parameter meaningless as well, except
to the extent that they should all describe a self-consistent hypothetical
drive. The ffs still works to layout things contiguously or at least nearby,
and this results in good performance even if the geometry is unknown.

The only real decision you get to make is the block and fragment size,
for NetBSD/alpha always use 8k/1k.
