Error: The operation would result in removing the booted kernel

[Lucas Alvares Gomes]

Creating a Fedora 24 [0] image on a Fedora 24 kernel booted with the same kernel version that the image has available will result in:

Workaround: Boot the host with a different kernel version

    Use rpm -e instead of dnf for cleaning old kernels

    If the running kernel of the system building the image
    matches the kernel that is to be removed dnf will fail.

    Repalce use use of dnf with rpm -e.
