Well, after yesterday’s lesson about getting the IBM RDAC to install for a not-yet-running kernel, I decided to take it a step further. Novell does have some documentation about KMP’s, which is actually rather good, especially the guide written by Andreas Grünbacher.

After a short tinkering, I got it actually working. I was kinda surprised, at how easily it actually is. One problem I still have to deal with, is modifying the %post, to generate the mpp-initrd image. For now, the KMP only contains the default %post, which updates the modules.* stuff.

  - Initial package.

Now, I’m kinda asking myself, why don’t more vendors submit their drivers to Novell in form of KMP’s … Anyway, I’m gonna send mine the LSI/IBM way, maybe they’ll pick it up …
