I'm installing Oracle and the Oracle install docs say to modify a couple of header files for shared memory and semaphores, then rebuild the kernel. On Solaris, this type of change is done in the /etc/systems file followed by a reboot. Hint, hint kernel guys... A few questions: Do I really have to build a new kernel? I read the README in /usr/src/linux and it said basically three steps: 1. make config 2. make dep 3. make bzImage I know there might be some more customization to do and there was mention of make modules and make modules_install if I am doing module stuff. But what I really want to start with is build the same kernel redhat releases. Is that just taking the defaults in make config and doing steps 2 and 3? What happens if I start dropping things like no IPX support or limit the number of disk or NIC types? I can predict my hardware, I understand it limits flexibility for future hardware changes. What does it do to kernel size and speed? Comments on whether this type of pruning is worth it? Normally I'd just test this out on my junk machine (gotta love vmware) but I don't really have time to experiment with this project. Appreciate your help and advice.
