I may have gotten it from reading the /usr/lib/kernel/install.d/51-dracut-rescue.install script directly. > I just manually remove the rescue vmlinuz and initramfs and > then run > /usr/lib/kernel/install.d/51-dracut-rescue.install add $(uname -r) "" > /lib/modules/$(uname -r)/vmlinuz > in the /boot directory to build a new rescue kernel from the currently > running kernel. Is there an option to do that also? i.e. I invoke dracut from the command line and it automatically does all that if a > rescue_build.conf file is present in /etc/dracut.conf.d/ > Well sort of. If you really want complete control over how the rescue kernels are installed one option is to copy the /usr/lib/kernel/install.d/51-dracut-rescue.install script to /etc/kernel/install.d and tweak it to do whatever you want under whatever conditions you want. As long as the script under /etc/kernel/install.d has the same name as the script under /usr/lib/kernel/install.d, it will override (i.e. run instead of) the one under /usr/lib/kernel/install.d.
