It does indeed persist, at least to my empirical knowledge. You will have to explicitly erase the flash, if you really want it erased. Also, afaik, you _must_ erase it the first time you use a new volumes-xyz.xml layout file. Not sure what happens if you don't, but I think that's what the docs said ..
