    Will 7.6.1 be available in CD format? Do you know if Knoppix will be made available in CD format?
    The uncompressed size of Knoppix V7.6.1 (without 'KNOPPIX/KNOPPIX1') is 9500 MB. To strip it down to CD size of 770 MB compressed (2200 MB uncompressed) you have to remove stuff of nearby 7300 MB (uncompressed) and you have to solve many hundreds of violated or broken dependicies.

    Even Prof. Knopper hasn't been sucessful until now, as he told me - among other things - sometimes ago in pm.

    At least fairly simple to get down to 3GB

    When doing purging operations, I have found it to be fairly safe to do the purging without persistence, then remaster and test, and continue with the next step also without persistence. The occasional packages to install during the process, don't need persistent store.
    Here is a fairly simple and safe way to get down to ca 3 GB: Drop games, science, education, tex and kde, plus a few other packages.
    The image produced by squashfs compression is ca 150MB smaller than simple cloop compression in this case, so there may be a case for a squashfs version of minirt.gz here.
    I don't think it should be impossible to get down towards 2GB, but the more we purge, the greater the risk for a crash. (And I don't think we should hope for doing better than Klaus Knopper himself )
    This will give a few hundred MB for user data. Question for the OP: How much is needed?
    Code:
    sudo apt-get update
    #  Groups
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep ^games | cut -d' ' -f2`
    sudo aptitude  purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep ^science | cut -d' ' -f2`
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep ^education | cut -d' ' -f2` 
    sudo aptitude purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep '^tex ' | cut -d' ' -f2`
    sudo aptitude  purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep '^kde' | cut -d' ' -f2`
    
    # Single or small sets of packages
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep eclipse | cut -d' ' -f2`
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep inkscape | cut -d' ' -f2`
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep scilab | cut -d' ' -f2`
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep scribus | cut -d' ' -f2`
     sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep pidgin | cut -d' ' -f2`
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep denemo | cut -d' ' -f2`
    sudo aptitude -y purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep amarok | cut -d' ' -f2`

    sudo aptitude  purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep phpmyadmin | cut -d' ' -f2`
    sudo aptitude  purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep mysql | cut -d' ' -f2`
    sudo aptitude  purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep gnumeric | cut -d' ' -f2`

    sudo aptitude  purge `dpkg-query -W --showformat='${Section} ${Package}\n' | grep ' vim' | cut -d' ' -f2`
    
    
    sudo aptitude -y purge `deborphan`

    Thank you Capricorny,

    and sorry for the delay. We just returned from a conference where we started the BatPro program in another city in Romania.

    With your script we managed to shrink down the ISO to 2.8Gb and probably if we search more we could go further. I like how targeted directly an entire category or set of programs.

    Regarding the use of another ISO, it's possible that we could go with an Ubuntu ISO. I don't know why but we had problems with nvidia cards in old computers where Knoppix 7.4.2 was loading a wrong nvu module and we were ending up with a black screen in graphic mode. This problem did not appear with Ubuntu 14.04.

    Please feel free to propose more strip down scripts. We use LXDE, wxPython, espeak and VLC.

    Regards,
    Rares
