      Build a cloop root filesystem

​

      cloop is a Linux kernel module that enables compressed

      loopback filesystem support. With it you can mount a

      compressed filesystem like a block device and seamlessly

      decompress its data while accessing it.  The majority of the

      software on an LNX-BBC is accessed in this fashion.
