I've done diffs for the existing files: /usr/src/sys/conf/files,
/usr/src/sys/sys/malloc.h,
/usr/src/sys/sys/mount.h, /usr/src/sys/sys/vnode.h, and
/usr/src/sys/kern/vfs_syscalls.c.
What I'm at a loss for is how to use patch to create a directory worth of files.
  I need
to add /usr/src/sys/rfs and /usr/src/sbin/mount_rfs to the system.  Is the best
way to
use patch for the delta, and a tar file for the new directories?

The history of the code has seen 64-bits, powerpc 603, powerpc 403, and intel,
so
the only hurdle left is the I-P Dept.

Thanks for any 'send-pr' help,
Dave.
