Yes, otherwise it would be racy, some other process could make a symlink
attack whatever you have in your home dir.

	mkstemp and mkdtemp (section 3)

allow for templates. Or the shell function

	mktemp

allows for templates and creation of dirs/files.

But are mkdtemp and mkstemp available everywhere we want to compile
luatex?

The man page of mkdtemp(3) is not very inviting:
   VERSIONS
       Available since glibc 2.1.91.


Best wishes
