Hi All,
Fedora 38
My rescue kernel is FC30.
How do I install the FC38 rescue kernel?
# dnf whatprovides kernel* | grep -i rescue <nothing>
And my search engine is not helping.
Many thanks, -T

$ grep -IR dracut_rescue_image /usr/lib/dracut /usr/lib/dracut/dracut.conf.d/02-rescue.conf:dracut_rescue_image="yes"
It looks like dracut_rescue_image is used back to at least F25.

# dnf install dracut-config-rescue probably is what you are looking for.

How do I get fc38's rescue image to show at boot time?

Make sure you have dracut-config-rescue installed. Then run:
sudo rm /boot/*rescue* sudo /usr/lib/kernel/install.d/51-dracut-rescue.install add "$(uname -r)" /boot "/boot/vmlinuz-$(uname -r)"
That will make the currently running kernel, with a suitable initramfs, be your rescue kernel.

There isn't one, it is just an ordinary kernel with all drivers available.

Always built locally.

I think you need to look at dracut.
The next time you are going to install a new kernel, delete the rescue vmlinuz and initramfs. The install will automatically build a rescue kernel from the new kernel you are installing (or maybe the kernel you are running, can't remember which).
Or, do the delete step, and run /usr/lib/kernel/install.d/51-dracut-rescue.install add $(uname -r) "" /lib/modules/$(uname -r)/vmlinuz

I've found that removing the rescue files from /boot and then doing a dnf reinstall kernel-core will do it.
Did just run it to make sure, paste has wrapping, but hopefully one can follow.

Hi Michael,
Worked perfectly. Excellent directions!
If you install the following statement into /etc/default/grub, and remake the grub menus either with grubby (maybe) or definitely with grub2-mkconfig, the menu build process it add a rescue entry into the grub menus for all kernels you have installed.
GRUB_DISABLE_RECOVERY="false"

Saw a while back that all you need to do is delete the rescue image from /boot and the /boot/loader entry. Then a rescue image will be created with the installation of a new kernel. blscfg will put it in the menu.
It has worked several times for me.
