A drop or two of glue between the end of the fingerboard and the front of the nut just makes sense. The glue will hold the nut in place but the joint will break easily if and when the nut needs to be removed. The nut to end grain joint should separate with little to no damage to the end of the fingerboard.

Hide glue should work fine; I use a drop or two of Titebond Original.
