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.

Patrick

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.

Code:

---

menuentry "KNOPPIX LOOPBACK"  {
        echo    Please Wait
        insmod loopback
        loopback loop (hd1,1)/isos/runtimelivecd.iso
        linux (loop)/boot/isolinux/linux bootfrom=/dev/sdb1/isos/runtimelivecd.iso 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
}

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 :D

Full quote and link to commercial software deleted

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.

Greetings again, patrick013.

In further review of this thread, I found a site which offers a program called
Runtime-Live-CD. The site also provides a checksum to verify the free download.
This site is at: https://www.runtime.org/data-recovery-live-cd.htm

In reviewing the material on this site it becomes apparent that a few-years-old
CD version of Knoppix has been used to provide an iso from which to make an
adapted Knoppix LiveCD of Version 6.7 or 7.0 which in turn would provide a desktop
from which to call-up additional runtime programs. These additional programs are
not free.

It is probably possible, but would be unnecessarily difficult to resurrect a working
frugal install from the outdated KNOPPIX image to be found within the Runtime iso.
At best, you will achieve getting a likely crippled and certainly outdated version of
Knoppix to work in this manner.

My suggestion is to abandon the Runtime-Live-CD approach and start over with
actual Knoppix iso material. This will also make the wiki suggestions more correct
for the material you are working with. As a further suggestion, perhaps use a
Knoppix 7.2 LiveCD series iso and make a LiveCD first before attempting to make a
frugal install. There is no 7.4 series LiveCD iso, unfortunately. Perhaps also,
re-consider even making a LiveUSB rather than a frugal install, since this will
be so much easier to do.

Checksums are still important, as indicated in my prior post,
and in addition use the built-in Knoppix checkcd as a further check that
the basic KNOPPIX compressed image is ok.

Well checked the md5sum, no problem. Tho built on Knoppix it is not a commercial product.
Just a linux iso so driveimageXML works in wine etc.. I could burn it to CD but thought
the loopback would be easier. No problem. For a few Windows backups might be good.
I have a copy of ActiveBootDisk the official MS supported backup program. So a CD burn
of their program would be OK then.

thanks for your response.
