    What is a "sdcard.img" ? Elaboration is required.

    But typically, no it wont work. Typically, you'll want to use dd,
    or tar. Then the partition that is meant to be bootable, needs to
    be marked as bootable using a suitable tool. Such as fdisk, or
    perhaps sfdisk.

    Such a workflow, would look something like this:

    Keep in mind this is Roberts build guide for  the beaglebone
    black, and is not intended in this context to be an exact steps
    example of what you need to do. But it should give you a rough
    idea of what all needs to be accomplished over all. *If* you're
    familiar enough with the Linux command line, and tools used.


Additionally, if you search the internet for "debootstrap how to" You'll probably find a lot of information on how one would create a rootfs, from scratch, and how to apply that knowledge for this purpose. But again, in this context, there will be a lot of superfluous information. So you'll have to parse what you read, understand what's going on, and take away what you need from it.
