There is, it's called updating to known good tinderbox build and basing 
changes off of that.

There is no reason why not to add such a thing, in fact it would be 
really handy for some of our users who need asserts, but sometimes can't 
clean up the entire code base.

Adding another option to tag asserts so that it was sort of like:

KASSERT((cond, section, "string")); would be interesting, then you could 
turn KASSERTS on based on "vfs" or possibly file by file.
