I need to rebuild the SL4.1 kernel to add support for JFS and XFS. Are there clever ways to do this? I'm familiar with the brute-force method. make menuconfig % to add JFS and XFS make bzImage make modules make modules_install cp bzImage, System.map to /boot mkinitrd to make a new boot image; I need to add my RAID driver which is not in the kernel tree. edit /boot/grub.conf to add the new kernel image I tried the kernel's 'make install' but that failed. Apparently, the kernel-release was not set up correctly. I'm guessing that this is set up in the spec file and since I was doing this manually, some things got left out. What I need is to build it with the given spec file, but I need the build to use my new config file. Do I simply add a patch file for the .config and fiddle the spec file to include it? I can do all this, but I'm curious if there is a cleverer way. Ken
