Okay, I think I now feel comfortable enough that I think I can unleash this on the world... I have made an extension to iso9660/RockRidge to allow for transparent uncompression of block-compressed files. Because the files are block-compressed, random access is fast; it uses a 32K blocksize which gets pretty good compression ratios (I got 2:1 overall compression on my SuperRescue CD; that includes a fair number of incompressible files.) The patches are available as: ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/filemap-2.4.4-1.diff.gz ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/zisofs-2.4.5-pre1-5.diff.gz (Both are needed.) Additionally, the user-space utilities (a program to compress and uncompress file trees, and a patch to mkisofs to generate the new RockRidge records for compressed files) are available at: ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/zisofs/ If you test this out, please let me know; I'd like to know if anyone actually cares about this... also, I would like to gauge if I have messed up stability anywhere. -hpa -- <[EMAIL PROTECTED]> at work, <[EMAIL PROTECTED]> in private!
