I finally bit the bullet and learned how to build it into my kernels so there are no extra files and except for a recent problem with Gentoo devs making changes to busybox defaults it's worked very well. The nice thing about building it into the kernel is that old kernels continue to work perfectly as best I can tell. Anyway, from my perspective it was worth learning. I'm just a user type, not a dev of any type.
