In general, I believe the distro kernels are more suitable for production use than a vanilla kernel. These companies are betting their support time and future revenue on their kernels working properly, and the distros take that very seriously. The fact that nobody actually ships a vanilla kernel should make it pretty clear the stock releases are not ready for the tasks our customers need them for. The fact that our customers pay us to add patches instead of using the stock kernel for free is also important. This doesn't make it a good idea to run rhas 2.4.9 based kernel in production with reiserfs, they were not horribly focused on reiserfs, especially when rhas came out. -chris
