That's true, but it is always good to explicitly list any and all
direct dependencies (and build dependencies) in a package anyway,
because things can change in the future.  For package A if you
depend on package B, and also need F, but B drags in C, which
drags in D, which drags in F already, so you do not put an
explicit dependency on F and your package does directly use F
itself, then in Fedora Core 8 when package D no longer needs F
anymore, it wont drag it in for you anymore either.  This
results in a problem 3 years from now for someone.

So if you know you need F, specify that you need F period, and
you never ever have to worry about it again.
