That's probably not what you think it is. By default the initrds have a
very limited number of drivers, intended to be the minimum required to
boot the current hardware. The rescue image has the full complement of
drivers so that if you change your hardware or move the drive to a
different computer, you will still be able to boot it. Unfortunately,
that initrd is never rebuilt with newer kernels and also doesn't
necessarily include 3rd party drivers.
My preference is for the rescue mode to use the most recent release
practical up to and including f30 (not 31!). I do now have Fedora live
on a USB stick, but as I noted (in different words) when I closed the
"prep. for upgrade" thread, it's glitchy. So I'd like to have this
second fall-back.
How do I rescue the rescue mode?
If you delete the existing rescue kernel and initrd from /boot, the next
kernel install will generate a new one. However, what you're really
looking for, you already have with the live boot. If you boot from the
live image, in the grub menu is a troubleshooting submenu. In there
you'll find the memtester option.
