Example of location of a home directory

Although both Joe and Sarah are registered as users on their local UNIX system, they belong to different departments; Joe is a postgrad student in artificial intelligence while Sarah is Head of the Math Department. Their respective home directories might be:

          /(root)
             |
             |
   ----------------------
     |              |
    /tmp          /home
     |              |
         ---------------- ... ----
         |         |             |
        /ai      /biol          /math
         |                       |
    ----------             ---------------
    |                                    |
  /joe                                /staff
                                         |             
                              ------------------
                                               |
                                            /sarah

The full pathname to Joe's home directory is /home/ai/joe - that to Sarah's is /home/math/staff/sarah.
