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 contain‐
       ing 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 rescan the directory. If a module is
       unloaded, its associated /system/object files disappear from the  hier‐
       archy  and  subsequent  attempts  to open them, or to read files opened
       before the module unloaded, elicits an error.
