Subject: Re: Regenerating rescue kernels (Fedora upgrade documentation)
ensure

grep exclude /etc/dnf/dnf.conf | grep dracut-config-rescue
(empty)
clean existing, to prevent exec blocking
rm -f /boot/vmlinuz-0-rescue-* /boot/initramfs-0-rescue-*
regenerate rescue kernels for currently installed kernels,
for _k in /boot/vmlinuz-[0-9]*
do
_v=${_k#/boot/vmlinuz-}
dracut --verbose --force --no-hostonly -a rescue /boot/initramfs-0-rescue-"${_v}".img "${_v}"
done
e.g., before,
ls -al /boot/{initram,vmlinuz}*

-rwxr-xr-x 1 root root 17M Apr 24 20:00 /boot/vmlinuz-6.14.4-300.fc42.x86_64*
after,
ls -al /boot/vmlinuz*
rescue kernels are big. make sure your /boot partition has enough space.
e.g., for these 3 kernels + rescue kernels,
ls -al /boot/{initram,vmlinuz}*
