Nice idea. It could probably work for p_frag, where the disktab equivalent
should be "fa", "fb", "fc", etc.

But there is nothing in disktab(5) which fits into p_cpg. Another problem is
that this field has another meaning for each file system:

UFS: cylinders per group
LFS: segment shift
ADOS: reserved blocks

And the ados file system needs the number of reserved blocks to calculate
the root block location...
