Chris G. Demetriou and Bill Studenmund helpfully pointed me
to bdevvp() in ffs_mountroot(). Silly me. My search was too dumb
(I was looking for stuff like "rootvp =").
Now, Ignatios Souvatzis asked a very sensible question -
why don't I use the libsa stuff?
That would certainly be the simplest replacement for the
existing Booter code, but:
1) By implementing all the VFS stuff, it means that I can also read
any type of filesystem (e.g. ext2fs, lfs)
2) If I ever get this stuff to work nicely on a 68k Mac, it can also
be used in the utilities that have to write to the filesystems
(the Installer) or newfs them (MkFs)
That is still a long way off, though.
