File systems questions
----------------------

1. Does recasting the familiar inode interface used for local file
   access into the vnode interface for remote file access support or
   violate the end-to-end argument of system design?

2. As disk track densities increase, it becomes harder to precisely
   line up all the tracks in one cylinder.  What problems does this
   cause, and what could be done to mitigate them?

3. Imagine you are designing a RAID system where each disk resides on
   a separate network node.  What problems would you face that the
   designers of traditional RAID systems do not have to deal with?
