Clonezilla / Patches / #19 ocs-iso functionality broken when booting via network PXE

Steven Shiau - 2022-04-04

For PXE booting, definitely you have to specify vmlinuz and initrd outside the root file system (filesystem.squashfs). We never have this issue with the original ocs-iso.
How did you setup your PXE in the server so that you have to patch the ocs-iso?

  It's the same thing we use here. We have used the original one in Clonezilla lite server and it does work well. Therefore I do not think this patch is required.
  Thanks anyway.

    You're saying I should be able to create an iso when clonezilla is PXE booted from the network, correct?
    
    I wonder what's causing this error message then?

      So under which GNU/Linux did you run that?
      It's recommended to run in Clonezilla live environment, as mentioned here:

        Since I have ocs_daemonon="ssh" set, I was logged in via ssh... it makes testing easier. The strange colors are custom for my rxvt-unicode terminal via ~/.Xresources :-)
        
        So the screenshot is of a clonezilla live environment (PXE booted from the network). Naturally, the same problem happens at a console... but, again, only if clonezilla is PXE booted from the network.
        
        I think you should be able to reproduce the problem without much trouble.

        Oh, please forgive me. I finally understood what you meant. So you boot Clonezilla live via netboot, and want to run ocs-iso to create a recovery iso file. Yes, in that case, that's true.
        Will try to improve ocs-iso and ocs-live-dev based on your patch. Thanks.

Also, assuming the patch is useful, I copy/pasted the following bash string replacement to report the script name:

${0##*/}

but in retrospect, I think this one is more readable:

${0/#*\//}

and may amount to the same thing; I'm certainly not the final authority on bash scripting.

  I think it's because the latter looks more like sed or perl to me.
  Naturally, this clears things up a fair bit...

This issue was addressed in Clonezilla live >= 3.0.0-18 and 20220419-*:
https://clonezilla.org/downloads.php
Please give it a try and let us know the results.
Thanks.
