I am looking at uiop/image.lisp and it looks like it should do what you
want out of the box.  At the very bottom of the file I see a call to
REGISTER-IMAGE-RESTORE-HOOK, and one of the elements of that list is
setup-temporary-directory.

So it seems like either this call is not happening properly or there's a
bug in setup-temporary-directory.  Is there any chance you could have
overwritten UIOP's restore hook?

Would it be possible for you to trace RESTORE-IMAGE and
SETUP-TEMPORARY-DIRECTORY to see what's happening? I confess to not
knowing whether TRACE will persist over image dumping....

Thanks,
