HOWTO: Build driver update disk for SLES

Okay, so we have this humongous ERP server we call the "Monster", with a, well, not-so-esoteric network card. We were in the process of upgrading it to SLES 10 SP4, but we hit a snag since SP4 doesn't have the most recent driver.

So it was off to HP we go, to search for the latest driver, which was in the form of a kernel module package (KMP). Using Novell's reference as a guide, we built a driver update disk (DUD).

1. Build the KMP to a usable RPM.
2. Create a build directory and extract the module.
3. Create the staging tree.
4. Populate the tree.
5. Create post-update script to workaround a SuSE bug in processing multiple RPMs.
6. Create MD5 sums.
7. Create package description.
8. Create information file.
9. Build ISO.
10. To use, add

    dud=1

    in the linuxrc boot option.
