Need help with zfs kernel module.

Ok, really right now I'm stuck at the spl kernel module (Solaris Porting Library). First, both spl and zfs create their own RPMs, which of course I'm not using but there's a few cases where the way they handle things are not covered in the RPM Fusion kernel module guidelines. I have the spl kernel module building fine. The problem I'm having is that with upstreams method it also produces a -devel kernel module package that has headers and symbols needed for the zfs kernel module to build. Do we have anything like that already? Since the -devel package seems to be kernel specific it will need to get built at the same time as the kernel module. Unfortunately I'm not currently using their own "make install" because it puts the modules in .../addon/... instead of .../extras/... so I'm installing the kernel modules manually. Which means I'm not getting the additional files. I guess I may have to go back to using their make install and just moving the files manually, then create a -devel sub-package to pic up the extra files. Then I have to figure out how to make akmods install them. Ideas? Thanks, Richard
