I personally don't see much benefit on this. The debug module is the
one used to debug the initramfs-framework script. If we ought to add
support for something like this, this should be done there.

A possible way to do so is adding in the module the init-verbose and
init-debug params and this to set bootparam_verbose and
bootparam_debug accordingly. This avoids changing the common code and
move this where it belongs.
