    How to fix the Knoppix 7.0 English DVD.

    Hello,
    I finally got my hands on the German version of the Knoppix 7.0 DVD
    which successfully passes the "knoppix testcd" test, and has the following md5:
    300586ae0d536b2522494c82d845534b *knoppix_7.0.iso
    For those who may be interested in correcting the few corrupted (and not critical)
    files included within the English version of the /KNOPPIX/KNOPPIX cloop file
    please find below the link to the correct data extracted from the German DVD:
    http://s94002264.onlinehome.us/grub/...PIX_70_fix.tgz
    and below the md5 of the correct files included in the above file:
    d6aafd5451b9b1700b5bcb393948b92c KNOPPIX/usr/bin/amd64-mingw32msvc-strings
    af9cbfed007c6bb158d80c7200a5e85c KNOPPIX/usr/bin/amd64-mingw32msvc-strip
    af9cbfed007c6bb158d80c7200a5e85c KNOPPIX/usr/amd64-mingw32msvc/bin/strip
    After copying the content of the /KNOPPIX folder and replacing the corrupted files
    by the content of the above KNOPPIX_70_fix.tgz file you may want to use the
    following command to recreate a corrected KNOPPIX cloop file:
    mkisofs -R -U -D -hide-rr-moved -cache-inodes -no-bak -pad KNOPPIX_folder | nice -5 create_compressed_fs - 65536 > KNOPPIX
    Then update the sha1sum check file for your new KNOPPIX cloop and recreate the iso.
    Please note that the above command requires really a lot of RAM to run properly
    and not have corruption as the whole KNOPPIX data content is piped using RAM.
    Is this the corruption problem that happened during the English remastering ?
    In all cases, I hope that this will be helpful to someone.
    Best Regards,
    Gilles

    How much RAM minimum do you suggest we need?

    'really a lot of RAM' is hard to quantify!

    How much RAM is required for a KNOPPIX cloop remaster ?

    Hi ICPUG,
    My guess is that in the worse case scenario (of a very slow computer) the amount RAM required
    for the pipe to work properly is the size of the data that you need to compress into the cloop file
    which in this case is about 9GB. So I would recommend the use of a swap file larger than 9GB.
    Best Regards,
    Gilles

    Why don't you use the option "-f"
    Code:
    create_compressed_fs --help
    as in the HowTo?

    You need a huge amount of space, either within RAM or within disk (swap file, swap partition or output file).

    Lower RAM footprint when using create_compressed_fs (with the -f option)

    Hi Werner,
    I did not know about this "-f" option and I did not check the remaster howto for quite a while.
    In all cases yes it does make sense to use the -f option to lower the RAM requirement even though
    I did not try it yet, but I will for sure use it in the near future, as well as the -L -1 (for lzip compression).
    Thanks for the suggestion ,
    Best Regards,
    Gilles

    PS: the help option for "create_compressed_fs" is "-h" (instead of --help)

    The Linux way to use options within shellscripts is longterm version like "--help". In some cases also shortterm version like "-h" will do the job.

    To avoid headache I always use "--help".

    Hi Werner,
    What I meant is that the "--help" parameter is not recognized by "create_compressed_fs"
    (but still prints a nice help message), as you can see below:
    # create_compressed_fs --help
    2 processor core(s) detected
    create_compressed_fs: unrecognized option '--help'
    Usage: advfs [options] INFILE OUTFILE [HOSTS...]
    ...
    Best Regards,
    Gilles

    Yes, this nice help message doesn't differ from the message you get using

    create_compressed_fs -h

    Knoppix 7.1 coming soon ?

    Hello,
    I just found this live CD using Knoppix as an engine:
    http://www.runtime.org/data-recovery-live-cd.htm
    and interestingly it is based on Knoppix 7.0 (or 7.1 ?)
    as it is using a new Linux kernel 3.3 and have a CD size.
    I wonder who is working on this Knoppix remaster ?
    Cheers,
    Gilles

    I don't know, who is working on this remaster.

    But klaus2008 did many tests with new Kernel versions for Knoppix 7.0
