Cramfs - cram a filesystem onto a small ROM¶ cramfs is designed to be simple and small, and to compress things well. It uses the zlib routines to compress a file one page at a time, and allows random page access.

Files on cramfs file systems are zlib-compressed one page at a time to allow random read access. The metadata is not compressed, but is expressed in a terse representation that is more space-efficient than conventional file systems.
