Yes.

That would be the correct thing to do.

That unfortunate misconception is built into many Emacs packages, hence
the effort to finally make this operation a no-op and move the seeding
of the PRNG to the Emacs init code.
> Besides, (random t) is documented in Emacs <24.3 and XEmacs.
Sure, but you still aren't supposed to re-seed a PRNG each time you want
a random number from it. Especially not with the seeding method that
Emacs used to use. Each Emacs session should call `(random t)´ exactly
once, in the user init file.

Achim.
