[GRASSLIST:4838] best way to grow a distance layer?

[William W. Hargrove]

I want to grow distance rings around some features in a large, high resolution
map.

Looks like r.buffer will do the job, but it only takes up to 60 buffer rings,
and this won't get me to the edge of the large map with a resolution of one
cell width.

Is there a single command in GRASS that will grow a distance layer out to the
edge of the map?

Thanks,

Bill H.
