    runtimelivecd frugal or loopback

    Hi,

    Have been trying to do a frugal install thru menu.lst (grub legacy)
    or a loopback install thru grub.cfg (grub2).

    Have followed the wiki info verbatim for other Knoppix iso's to
    no avail. This is the runtimelivecd.iso which is a Knoppix system
    recovery disc. Used the isolinux.cfg as boot parameters to no
    avail and also some other boot parameters (bootfrom=) on both
    grub and grub2. No go.

    Error messages include cannot find KNOPPIX on /isos/runtimelivecd.iso
    and Searching for Runtime Live cannot find.

    Like it's looking for a CD drive and can't find it tho boot parameters
    give the iso location.

    So, rather than throwing dice at my grub.cfg all day long I need to ask.

    For a grub.cfg loopback what is the proper stanza for this iso ? menu.lst
    is also a possibility but my flash drive has grub2 on it and that would be great
    if a loopback in there with grub.cfg completed boot OK then.

    thanks in advance.

    I suppose you are speaking about this Wiki and the method ISO install to HD.

    Please tell us the menuentry you've append within '/etc/grub.d/40_custom'.

    Yes, that is the main source for info.

    Here are 2 stanzas I tried before giving up. And thanks for the response.

    Code:
    menuentry "KNOPPIX LOOPBACK"   {
            echo     Please Wait
            insmod loopback
            loopback loop /isos/runtimelivecd.iso
            linux (loop)/boot/isolinux/linux iso_filename=/isos/runtimelivecd.iso myconfig=/mnt ramdisk_size=100000 lang=en apm=power-off initrd=minirt.gz nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 noswap tz=localtime debug
            initrd (loop)/boot/isolinux/minirt.gz
    }
    
    
    menuentry "Knoppix Runtime" {
               echo     Please Wait 
             # set root=(hd0,1)
               loopback loop /isos/runtimelivecd.iso
               linux (loop)/boot/isolinux/linux root=(loop) toram bootfrom=/dev/sdb1/isos/runtimelivecd.iso
               initrd (loop)/boot/isolinux/minirt.gz
    }

    If the ISO had a loopback.cfg file I could boot it with this line:

    configfile /boot/grub/loopback.cfg

    So easy but it doesn't.

    If you've really read this Wiki, why doesn't you use the example there for the menuentry within '/etc/grub.d/40_custom'? The examples you've posted cannot work.

    I did just today, the stanza wouldn't even start. So I tried some modifications
    and at least it tried to look for the iso. The exact config there for sdb1 (flash drive)
    is a no go.

    thanks for the response, if you think of anything else let me know.

    }
    Delete the blue part, insert the red part.

    No go, wish I could say otherwise.

    My loopback and frugal install syntax keeps getting a result where it says that

    Cannot read Knoppix from dir from iso /dev/sdb1/isos/runtimelivecd.iso (or similar message)

    I'm tempted to say my flash drive needs to be FAT32, this one is a linux filesystem.

    Anyway, here's the actual iso location, no rush at all, if ever you can get a loopback or frugal
    install stanza to work for grub2 let me know.

    Thanks for taking a look, have a good one.

    Patrick

    The description in the Wiki is tested for origin Knoppix version. If you use a modified Knoppix, you may seek help by the these people which created this CD. And it's a bad joke, it they wrote: "We do not provide support for the Runtime Live CD,"

    If you are using a 'commercial product', then it is possible that the iso is damaged.
    This can be determined by doing a checksum comparison, like md5sum if this has been
    included in what you have received.

    If you have no such checksum, then one avenue you might consider is downloading a
    new iso and checksum from a Knoppix site or mirror. This would require a reasonably
    fast internet connection, but is otherwise free.

    Knoppix mirrors are listed at:
    http://www.knopper.net/knoppix-mirrors/index-en.html

    The latest version is the Knoppix 7.4.2 DVD.
    I usually use the ftp site:
    ftp://ftp.uni-kl.de/pub/linux/knoppix/

    There is not usually any recovery from a bad iso except getting a replacement.

    Good Luck & HTH.

    Well it's a free linux iso with their driveimageXML wine'd into it.
    Thought I'd recommend it here to some people.
    The md5's check out OK btw, just a weird iso that needs a full install then.
    thanks for the response.
