You gotta keep your "/"'s straight. The kernel will boot of off a
physical devices - pretty much required. At that point, you can use
boot.config to load modules from that device, including any needed to
keep your driver happy. Set the vsf.root.mountfrom to tell the kernel
what where to find what's going to become the root file system when it
gets to that point.
The process is documented in the man pages, starting with say
boot(8). Read through that and some of the "SEE ALSO" pages.
