NAME
     objfs - Kernel object filesystem

DESCRIPTION
     The objfs filesystem describes  the  state  of  all  modules
     currently loaded by the kernel. It is mounted during boot at
     /system/object.


     The contents of the filesystem are dynamic and  reflect  the
     current state of the system. Each module is represented by a
     directory containing a single  file,  'object.'  The  object
     file  is  a  read  only  ELF file which contains information
     about the object loaded in the kernel.


     The kernel may load and unload modules  dynamically  as  the
     system runs. As a result, applications may observe different
     directory contents in /system/object if they repeatedly res-
     can  the  directory. If a module is unloaded, its associated
     /system/object files disappear from the hierarchy and subse-
     quent  attempts to open them, or to read files opened before
     the module unloaded, elicits an error.
