There is a point; mkdtemp() uses the passed variable for both input and
output. On function enter the file pattern is stored there, on function
return the actual dirname that was created is stored there. Calling
mkdir(STATEDIRTEMPLATE) would lead to sigsegv I guess. Let me try. Yeah,
my guess was right.
