With current bacula, you could actually do it, too. You would have to 
manually purge the oldest full backup. But that only works for one-off 
situations, not on a regular basis.

I believe that's how it already works. You would set volume retention to 
1 day or so. The volume won't expire as long as there is still at least 
one unexpired job on it. And that job expiration would be controlled 
with this new setting.
