FWIW, I don't recall any reason why it shouldn't work with unexec, either. To the best of my recollection, unexec was generally broken at the time I wrote the patch; I fixed unexec and then it worked without purespace, but the unexec fixes never made it into master until Eli re-did them a while later. (IIRC, this patch predates the nativecomp merge and that affected pure space a little, so that probably needs to be kept in mind.) Pip
