    Knoppix 9 dual boot from iso on win 10 ntfs nvme partition.

    Hi Klaus,
    I hope my email finds you and your loved one healthy and happy.
    I am just sharing some findings that you may be interested in adding into your next Knoppix release. I finally managed to dual boot natively Knoppix 9 from the iso image located in the Win 10 ntfs partition of the nvme ssd drive of my new machine and that was more complicated than I initially thought. Most of my problems came from the outdated version of busybox in the initrd which 1) was not seeing the large (>255) major device nodes and 2) could not see the content of the mounted ntfs partition because it was too large. After recompiling a standalone version of busybox with the proper options (and there is quite a few of them that matter) I also had to update the init boot script to replace all the "let" bash calls by "$(eval )" because I could not figure out how you got busybox to recognize that "let" applet. Finally I also had to add a couple lines in the init script to add the missing device nodes for the nvme partitions because udev is not yet running to discover them in the early stages of the boot. BTW, I also added support to boot from mmc cards which are available on most new laptops. If you are interested I will be more than happy to share my updated initrd which contains the new: init script, busybox and also some missing kernel modules (fuse, virtual machines hardware and all network cards support).
    Best Regards,
    Gilles

    Good, but from where can we get iso image - Corona Lockout

    Can you share the Ver 9 - EN iso image, know it is huge, but will be useful for knoppix users.

    U can use sourceforge or google drive.

    Thanks for sharing.

    Great!
    Seems to me that this should be merged into the standard distro if it isn't already?
    Would be nice to have the busybox updating recipe too, plus possibly just the patched init script.
