Is it possible to define which modules mkinitrd should add to the initrd? I have a custom initrd, but after every kernel upgrade, it recreates the initrd. When it does this, I loose the extra module I need, so I end up recreating the initrd myself again. I know in Ubuntu and Debian there is a file somewhere in /etc/sysconfig that defines the modules to use when building the initrd. But I have yet to find this file in Fedora.
