I run into this every time I upgrade Fedora, but I always forget to

In the Upgrading Fedora docs (https://docs.fedoraproject.org/en-US/
quick-docs/upgrading-fedora-offline/#sect-update-rescue-kernel <https://
docs.fedoraproject.org/en-US/quick-docs/upgrading-fedora-offline/#sect-
update-rescue-kernel>) one of the optional post-upgrade steps is
updating the rescue kernel. The documentation linked says:
The rescue kernel regeneration process can be automated by installing
the dracut-config-rescue package.
sudo dnf install dracut-config-rescue
Once installed, the rescue kernel will be regenerated as long as dracut
is the initrd generator. See /usr/lib/kernel/install.d/51-dracut-
rescue.install for details.
This seems to be incomplete or incorrect, because that package is
installed but I've never had rescue kernels generated. The referenced
file (/usr/lib/kernel/install.d/51-dracut-rescue.install) isn't
particularly useful to be referenced for details because it's a shell
script with no user documentation.
Before I dig in and become a dracut expert... is this an easy doc fix
for someone familiar?
That doc page is a bit unclear. That package will cause the rescue
image to be created if it doesn't exist. You only need to do the "rm"
part and the next kernel (re)install will re-create the rescue images.
