I had thought that they would come from the .config file from either the kernel-source.rpm or the kernel-devel.rpm for my current kernel. But these two files are different. I run the latest kernel, namely linux-2.6.30.x86_64 . In particular, is my current kernel PREEMPT or VOLUNTARY_PREEMPT? Any way to find this out? I know I can get the kernel I want (PREEMPT) by rebuilding, but it would be nice to avoid this, and also to be able to settle this question in general.
