There are two versions maybe both dated?

1. http://www.kanotix.com/index.php?module=pnWikka&tag=BootFromIso

Quote:

Now what if you don't want to just copy it to KNOPPIX/KNOPPIX.ISO, well then you have choices in how to build up the path it will look for:
fromiso=path/to/KANO*.iso
Makes Kanotix look for path/to/KANO*.iso

then

Quote:

knoppix_iso_dir=path/to/
Makes Kanotix look for path/to/KNOPPIX.ISO

knoppix_iso_name=KANO*.iso
Makes Kanotix look for KNOPPIX/KANO*.iso

which is confusing. And then

Quote:

fromhd=/dev/hdXN?
Makes Kanotix only check the specified device. Unless you use this Kanotix will check your drives as it would when looking for the cd.

2. http://www.kanotix.com/FAQ-id_cat-62.html#q297
& http://kanotix.com/FAQ-id_cat-63.html#q298

Quote:

With this cheatcode you can start from an iso out of a partition
Requirements:
- a functioning grub (on a floppy, a HD-Installation or from the Live-CD)
- a KANOTIX ISO Image e.g.: KANOTIX-2005-04.iso

First we choose a place for the iso and 2 files we need, so we get shorter names.
# mkdir /media/hda5/kanotix
# mv KANOTIX-2005-04.iso /media/hda5/kanotix
mount the iso image:
# mkdir -p /mnt/test
# mount -t iso9660 -o loop,ro /media/hda5/kanotix/KANOTIX-2005-04.iso /mnt/test
copy the files miniroot.gz and vmlinuz
# cp /mnt/test/boot/vmlinuz /media/hda5/kanotix/
# cp /mnt/test/boot/miniroot.gz /media/hda5/kanotix/
customize grub
### ISO boot
title Kanotix 32bit from ISO
kernel (hd0,4)/kanotix/vmlinuz ramdisk_size=100000 init=/etc/init fromiso=/kanotix/K*.iso noprompt noeject lang=en apm=power-off nomce quiet
initrd (hd0,4)/kanotix/miniroot.gz

Assume the second to be more appropriate. So, on my existing system I have created a top level directory '/Hellfire'

Code:

# mkdir /Hellfire

$ mv /kix/kanotix-2.6.38rc6.iso /Hellfire

$ ls -l /Hellfire

-rw-r--r-- 1 ik ik 1131413504 May 8 01:58 kanotix-2.6.38rc6.iso

# mkdir -p /mnt/test

# mount -t iso9660 -o loop,ro /Hellfire/kanotix-2.6.38rc6.iso /mnt/test

# ls -l /mnt/test/live

-r--r--r-- 1 root root 26399 Mar 2 04:47 filesystem.packages

-r--r--r-- 1 root root 1103929344 Mar 2 04:46 filesystem.squashfs

-r--r--r-- 1 root root 19970691 Mar 2 04:47 initrd.img

-r--r--r-- 1 root root 165084 Mar 2 04:47 memtest

-r--r--r-- 1 root root 4533424 Mar 2 04:47 vmlinuz

No 'miniroot.gz', so assume changed to be 'initrd.img'

Code:

# cp /mnt/test/live/vmlinuz /Hellfire

# cp /mnt/test/live/initrd.img /Hellfire

# ls -l /Hellfire

-r--r--r-- 1 root root 19970691 May 8 13:25 initrd.img

-rw-r--r-- 1 ik ik 1131413504 May 8 01:58 kanotix-2.6.38rc6.iso

-r--r--r-- 1 root root 4533424 May 8 13:24 vmlinuz

GRUB (Version 0.96) booting crashes!

Code:

# ISO boot

initrd (hd0,0)/kanotix/initrd.img

Code:

# ISO boot

initrd (hd0,0)/Hellfire/initrd.img

OR Shorter Image Name

Code:

# mv /Hellfire/kanotix-2.6.38rc6.iso  /Hellfire/hf.iso

# ISO boot

initrd (hd0,0)/kanotix/initrd.img

All give rise to the following output:

The Hellfire 2011-05 way is

cd /etc/grub.d
wget -N http://kanotix.com/files/fix/grub2/conf ... re_gfx_iso
chmod +x 666_kanotix_hellfire_gfx_iso

<change the file to match your system>

update-grub

Well you see not every part on the Wiki is up-to-date. There is a lack of men power to hold the Wiki in a good shape. Feel free to help and fix it. I like to see that the people take a lot at it, most people know that it is not in the best shape and ignore it completely. That's the wrong attitude to change the situation. So you are really welcome to help.

Thanks, TheOne

which doesn't work cos I need to get Grub2 Traurig

btw couldn't help noticing that the '666..' script

Code:

set isopart=/dev/sda1

set isopath=/Hellfire

set isoname=hf.iso

...

menuentry "Kanotix Live - EN" {

   search -sf /${isopath}/${isoname}

   loopback iso /${isopath}/${isoname}

   linux (iso)/live/vmlinuz fromiso=${isopart}/${isopath}/${isoname} boot=live config utc=yes locales=us quiet

   initrd (iso)/live/initrd.img

}

...

woud give rise to double // slashes,

Code:

   search -sf //Hellfire/${isoname}

   loopback iso //Hellfire/${isoname}

   linux (iso)/live/vmlinuz fromiso=${isopart}//Hellfire/${isoname} boot=live config

and would it matter?

i see no reason for //, can you tell me which bootloader you use? grub2 is really common.

Grub 1 can not be used that way, there is no loopback support. In that case you extract the live dir - best rename it to kanotix and use live-media-path=kanotix as extra option to the default options - but WITHOUT fromiso option - or extract just kernel + initrd and use fromiso.

There is a rider to be appended here.

If there is a top level directory of the same name, as that given in 'live-media-pathh=' , in another partiition as well, then that directory could be used resulting in a crash thru picking up the wrong version.

Thats correct, you can specify

live-media=/dev/sdx

This would be a good time to link to the Debian Live wiki on how to add a "persistent home" to your "poor man's installation".

The short version:

Create and format a loopback file named "live-rw"
Put it at the root of a formatted partition (I'd guess it has to be a different partition than the one you have the kernel, initrd, and sqashfs images saved to)
Put the cheatcode "persistent" in your kernel line

So your GRUB1 (not GRUB2) entry might look like this. (In this example the kernel, initrd.img, and squashfs image are saved at /dev/sda3/mnt/kanotix and the loopback image is at the root of another partition, both ext3-formatted.)

Code:

title           Kanotix PMI

root (hd0,2)

kernel /mnt/kanotix/vmlinuz \

    live-media-path=mnt/kanotix \

    boot=live \

    config \

    utc=no \

    locales=en_US \

    timezone=America/Los_Angeles \

    quiet \

    persistent

initrd /mnt/kanotix/initrd.img

boot

for persistence I use a separate partition rather than a loopback file. I give a label to this (ext3-formated) partition: live-rw.
The entry "persistent" in Grub will then cause all changes made to the live system to be put into this live-rw-partition. Upon reboot these changes are loaded into the live system. They also can easily be inspected there.......

@eco2geek

The "/mnt" looks weird in your example. Also the last "boot" is not needed.

You're right, it works equally well without "boot" at the end and with "live-media-path=/mnt/kanotix".

Is there a replacement for the "noeject" cheatcode, which no longer works?

Do you mean

Code:

# Create an empty ramdisk image

   $ dd if=/dev/null of=live-rw bs=1G seek=1 # for a 1GB sized image file

# Make it an ext2 mountable file system

   $ /sbin/mkfs.ext2 -F live-rw

Seems to me to be more flexible to have a file which one can move around, rather than to be bound to a particular partition.

Why? Are you planning on moving around the 1.1 GB squashfs file between partitions, too? Geschockt

Seriously, those instructions say the "live-rw" file just has to be at the root of a partition that can be found and read. It's not tied to any particular partition.
