This is incorrect.

Execute only creates a temp file if it thinks that some parameter substitution
(angle brackets, or .bra and .ket replacements) are involved.

The initial startup-sequence cannot have parameter substitution,
so no temp file is created when you boot a disk.

Recall that if T: is not yet assigned, execute tries to use :T.  If a
temp file was created, you could never boot off a write-protected disk!

Not so.
