=>	What are "vnodes"???
=
=In a nutshell...
=
=Vnodes are very similar to the System V file system switch.  They provide
=a layering between the generic file system activities and the file system
=specific activities so that you will not have to change any code in the
=generic layer when you want to add a new file system type.  
=
=This is a part of the system that you will never have to deal with unless
=you are adding support for new file systems to the kernel.

Thanks, Conner.  I guess I had better ask the rest of the questions.  :-)

What is the SV file system switch?  Is it true that vnodes and inodes
are not at all related?
