Yes. We already have RPMs that do that. We compile open-iscsi out of
tree. Our only problem is that because it uses header files from
/usr/src/linux/include/scsi/, we need to replace the old h files with
the new h files for the compilation time (and then restore the old
files). I guess that there might be a better way to do that (without
having to replace the h files in the kernel tree). Do you know how?

We plan to install 3 packages:

   1. open-iscsi - similar to the current open-iscsi package (contains
      config files and userspace programs).
   2. open-iscsi-kernel - kernel modules
   3. open-iscsi-devel - h files. We install it only if the kernel
      source code exists. This is necessary if you want to develop for
      open-iscsi.
