In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This is a Linux-specific extension to RockRidge which lets you store
data in compressed form on a CD-ROM and have it transparently
decompressed when the CD-ROM is accessed. See
<http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
necessary to create such a filesystem. Say Y here if you want to be
able to read such compressed CD-ROMs.
