Just to add a little something for flavor, I've found it useful to keep my config file elsewhere and use a symbolic link from /usr/src/sys/i386/conf, i.e. # cd /root # mkdir kernel-config # cd kernel-config # cp /usr/src/sys/i386/conf/GENERIC ./MYKERNEL # cd /usr/src/sys/i386/conf # ln -s /root/kernel-config/MYKERNEL Thus, editing, config and compilation works perfectly by the book, but if I feel like it, I can nuke /usr/src/sys entirely and reinstall the kernel sources without losing the precious customised config file. Of course it is no different from backing up the config file before reinstalling, but I've found it convenient a couple of times when noodling with my kernels. Regards, -Jan Christian
