I recently had the pleasure of looking at this code, and I think that this could be shrunk down further but it would require a functional change as to how things work with loader.conf, etc. I'll hash out the ideas on arch@ I had in mind after I let them stew a bit longer, but I think that boot[2] could be simplified more.
