    im trying to add an OS to berryboot for my raspberry 3



    looking at the website below

    http://www.berryterminal.com/doku.php/berryboot/adding_custom_distributions


    the 1st command I don't understand what does it mean? Does it mean I copy the image from a folder like home... Or does it mean I should copy the kernel.img from the usb?

    $ sudo kpartx -av image_you_want_to_convert.img
    add map loop0p1 (252:5): 0 117187 linear /dev/loop0 1
    add map loop0p2 (252:6): 0 3493888 linear /dev/loop0 118784
    $ sudo mount /dev/mapper/loop0p2 /mnt
    $ sudo sed -i 's/^\/dev\/mmcblk/#\0/g' /mnt/etc/fstab
    $ sudo mksquashfs /mnt converted_image_for_berryboot.img -comp lzo -e lib/modules
    $ sudo umount /mnt
    $ sudo kpartx -d image_you_want_to_convert.img

    It just means you tell kpartx which image file to use. There's no copying necessary.
