# get rid of the old
v.category type=centroid op=del
# create some new sequential ones
v.category type=centroid op=add cat=1 step=1

(cat= is the number it starts counting from)

if you need the cat to match the seed point, use v.distance as earlier
suggested. and do beware of what becomes of overlapping areas.
