NAME

       dcfs - Compression file system

SYNOPSIS

       #include <sys/filio.h>
       #include <sys/fs/decomp.h>

DESCRIPTION

       The  dcfs  filesystem  is  a layered filesystem that you use to compress data when writing to a file and decompress upon read.  The primary
       function of the dcfs filesystem is to compress individual files when constructing a boot archive and when reading or booting from  the  ar-
       chive.

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
       hierarchy and subsequent attempts to open them, or to read files opened before the module unloaded, elicits an error.
