========
modprobe
========
Allows to configure specific modprobe options on the image.
It contains the following functionalities:
1. Ability to blacklist specific modules using modprobe.d/blacklist.conf.
In order to use set DIB_MODPROBE_BLACKLIST to the name of your
module. To disable multiple modules you can set DIB_MODPROBE_BLACKLIST
to a list of string separated by spaces.
Example:
export DIB_MODPROBE_BLACKLIST="igb"
2. Ability to copy specific files into /etc/modprobe.d directory, so it
allows to configure settings with freedom. To achieve that, the files
to be copied needs to be placed inside an specific modprobe.d directory
of the element.

features:
- Add new modprobe element. This element will replace
modprobe-blacklist element. It wil still have the
blacklist functionality, but it also adds the feature
of passing a complete file with settings to the
modprobe.d directory. Adding this functionality, that
will allow elements that depends on this module, to
just copy the specified files to the final directory.
