Do you have some hints or a link describing how to do that?

I've read up a little on %trigger but I'm not sure if it can be used
in this case since akmods basically builds an RPM package from a
source RPM package and installs it. If I try to use %triggerin then
I'm already in an RPM session so I don't know how I could trigger an
install. Currently akmods gets around that by putting a script in

If %trigger can handle this then I'd really like to know how because
that would help fix the problem of a new kernel install without the
accompanying kernel-devel package.
