Are old rescue kernels still useful? (6 years?)
Yes -- they will let you boot into the system. The rescue initrd includes
all available drivers and so can boot even if the drive is in a very
different system from the one it was installed on.
Are there automated or manual procedures to update
a rescue kernel?
There's generally no reason to. But you can with
/etc/kernel/postinst.d/51-dracut-rescue-postinst.sh $(uname -r)
/boot/vmlinuz-$(uname -r)
I am on F33, but I don't have such a file. What creates it, or where
does it come from?
Are there best practices for rescue kernel update?
If there are, I've missed them.
That's because the best practice is generally to not worry about it.
