   Generally there are ways to use dd with the appropriate /dev/<file>
   to get at disk blocks without going through the file system.  You
   may need to know a lot about the internals of the file system to
   work out which block.

   As far as "everything is a file", I think that actually failed with
   early UNIX in the late 60's or early 70's.  If you can't find
   at least two namespaces in multiuser mode you're not thinking
   very hard.  But there are still a lot of things hanging around in
   file name space that don't really need to use up inodes.
