Can a directory in Linux partition be used instead of a persistent image?

[rajibando]

Like we use knoppix cheatcodes in grub.cfg how can we pass on those codes in case of ext4 persistant partition while booting to knoppix live in flash-drive?
</br>Thank you , belately, and sorry _/|\_ for being late.

Many of the Linux distributions ..

First of all, Knoppix isn't a Linux distribution. Many tricks you'll do with a distribution, you cannot do with Knoppix.

Why do you want to use a ext4 partition instead of a ReiserFS partition? ReiserFS is a proofed filesystem and KK does use it with good reason.

With the new Knoppix versions you don't need to copy flash-knoppix2. You can either use flash-knoppix from the command line or select it from the menu. If you use the command line, you'll see the possible options by

flash-knoppix --help

If you'll try the description of posting #8, you doesn't need an extra cheatcode; the content of 'knoppix-data.inf' is enough (bit I didn't tested it).

Good Morning, Mr. Schulz! And thank you for writing on this thread. I will try to answer to your specific queries point-wise:

(1) I am compelled to use 7.2.0 because only it allows me to install the proprietory NVidia driver for my laptop. I know you will frown upon my using a proprietary driver on my free and open source system, but nouveau, nv, framebuffer etc., make a mess of my system - they stall it.

Moreover, the HCL laptop I bought six years back is defective. If the system doesn't use the GPU it uses the CPU, the laptop heats up and switches itself off. Many power-offs damage the knoppix-data.img

If you see my other posts on Knoppix 7.4.2, like:

(a) Why 7.4.2 doesn't have xorg.conf file, why /etc/X11 is read-only?
(b) Knoppix 7.4.2 presents xscreensaver with GUI
(c) [Attn: Prof.Knopper] Incompatibility of NVidia graphics cards with Knoppix
you will see that I had problems with it.

(2) I have been successful in using a flash-knoppix aided by Blacksimon's suggestions, using an entire ext4 partition rather than the raiserfs knoppix-data.img. It is good for me to use the ext4 filesystem as I can recover data after a crash.

(3) To use knoppix-data.inf file I would need to know the list of codes that I I can pass to knoppix during boot ups. Is there a help file on knoppix-data.inf with a list of options?

I hope I have been able to explain myself.

Once again, I thank you for writing to replying to my queries.

Regards,
Rajib

Hi rajibando,
For the use of knoppix-data.inf you did not need any cheatcode.
The Linux initial RAM disk minirt.gz is a temporary root file system that is mounted during system boot to support the boot process. The minirt.gz contains various executables and drivers that permit the real root file system to be mounted, after which the initial RAM disk is unmounted and its memory freed.
Inside minirt.gz there is a file called init, this takes care of controlling the presence of the file knoppix-data.inf, read what is written inside and mount the persistence partition thanks to the instructions found.
If I remember, to take a look: gunzip -c minirt.gz | cpio -ivu --no-absolute-filenames.

Greetings Blacksimon & rajibando.

FWIW, init shows up at /init on both Knoppix 7.2 LiveCD & 7.4.2 LiveUSBs.
No need to decode the minirt.gz. Point Leafpad, or better yet, Geany at /init
to study the inner workings of Knoppix.

Dear Simon,
Both Utu and I found out that we can indeed pass cheatcodes through code, bypassing the Boot prompt, to Knoppix even in the flashdrive scenario. I request you to look at this Reply No.5 & 6
Thanks, Simon & Utu, for sharing your knowledge with the forum members. We will be enriched by these discussions.
