    toRAM bug?

    Hi people,

    I've added Knoppix to my DVD, which uses Isolinux as bootloader.
    no problem there.

    however, the DVD is about 3GB.

    when I type 'knoppix toram' , it goes copying, but complains about a full Ramdisk. from further output I see it tries the entire DVD content!

    toRAM parameter is only used for copying the KNOPPIX file to the ramdisk (not the entire disc!), or am I wrong here?

    any help / comments appreciated
    regards,

    Bernd Blaauw

    Check the size of that Knoppix file. It's nearly the size of the whole CD. All of Knoppix is compressed using Cloop. You need to have around 1gig of ram to use the toram option. Optionally, you can remaster the cd and remove unwanted applications or just copy the image onto your hd and boot from there like this: "knoppix tohd=/dev/hda1"

    actually,

    I *do* have 1GB,
    using the toram option,
    Knoppix says something about
    "please hold"

    and then it should copy the file KNOPPIX to RAM.
    nothing else.

    unfortunately my Linux knowledge is almost zero so if I use a cd I can't see if it copies only the Knoppix file, or entire contents..

    I found the "error". irritating.
    LINUXRC in the boot-image: line 265..270

    /bin/mkdir /cdrom2
    if [ -n "$COPYTORAM" ]
    then
    # Hey, we could use some fancy dialog skript here )
    echo -n "${CRE} ${GREEN}Copying KNOPPIX CDROM to ${MAGENTA}ramdisk${GREEN}
    /bin/mount - tmpfs -o size=800M /dev/shm /cdrom2
    if [ -z "$NOCD" ]
    then
    /bin/cp -a /cdrom/* /cdrom2 # Comment
    else
    /bin/cp -a /cdrom/KNOPPIX/ /cdrom2 # Copy only KNOPPIX-dir as we
    fi

    OK, found it. Now find a way to remedy it.
    (yes, I know the above patch, but how to create boot.img again
