In GNU or ksh93? It's merely semantics, I think,; you can't make sure that a filename is unique other than creating it with O_EXCL so we need to unlink and we're certain that the file was unique at some point in time. I think they have the same "root" but someone didn't properly clone mktemp(). Casper
