When looking for information on proper kernel module SRPM packaging on #centos, I was told that the real trick lies in proper interaction with Yum -- i.e., proper placement of version strings, upgrade behavior, etc. I'm not terribly familiar with building SRPMs, let alone kernel-related packages, but it makes sense that playing nice with Yum would be a very good first priority when doing so. Are there established guidelines (or better yet, specific HOWTOs) for assembling driver SRPMs to this particular end? Thanks... -Phil
