Sadly, they fundamentally misunderstood the "everything is a file" paradigm of *nix. It's not that everything is an extent of octets, it's that everything has a directory entry so C programs can use the open call to create a file handle. It might be more appropriate to say "Everything looks like a file in the file system and most every operation on a thing represented by a directory entry goes through a filehandle."
