If not, then the kernel module driver gets rebuilt and released as a new build for that situation. That provides a consistent upgrade path and keeps people from having to hold back kernels. The idea isn't to keep people from getting new stuff, but to ensure that everyone is able to keep up reasonably well. -- 真実はいつも一つ！/ Always, there's only one truth!
