3 namespace \- structure of conventional file name space
7 After a user's profile has run, the file name space should adhere
8 to a number of conventions if the system is to behave normally.
9 This manual page documents those conventions by traversing the
10 file hierarchy and describing the points of interest.
11 It also serves as a guide to where things reside in the file system proper.
12 The traversal is far from exhaustive.
14 First, here is the appearance of the file server as it appears before
15 any mounts or bindings.
