OBJFS(7FS) File Systems OBJFS(7FS)


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