It's *much* better to cause a clean break. That way people will notice it, and can fix it (and it will be an easy fix). An unclean break might leave people with things that look like they work, but don't. That's a lot more dangerous. Same reason I'm also +1 for Stephens suggestion to put all things that should not be in a base backup into the same directory. That may break things now, but it will simplify things down the road. And doing it at the same time as renaming these things makes a lot of sense, because it causes breakage that tool-builders *have* to look at, and then they will hopefully also notice the other change. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
