+ 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.
