Before doing this, a first step would be to delete the unneeded

We already do this for modloop. But to do it for the package, would
need a list of files needed to be maintained. I believe about half of
the package can be just deleted based on our module configuration and
specific kernel versions.

See for
how to get info on what firmware is required by the kernel modules.

If the package is still too large after this, doing splitting might be
an idea.
