.SH NAME
objfs \- Kernel object filesystem
.SH DESCRIPTION
.sp
.LP
The \fBobjfs\fR filesystem describes the state of all modules currently loaded
by the kernel. It is mounted during boot at \fB/system/object\fR.
.sp
.LP
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.
.sp
.LP
The kernel may load and unload modules dynamically as the system runs. As a
result, applications may observe different directory contents in
\fB/system/object\fR if they repeatedly rescan the directory. If a module is
unloaded, its associated \fB/system/object\fR files disappear from the
hierarchy and subsequent attempts to open them, or to read files opened before
the module unloaded, elicits an error.
