+ 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.
