Found this which seems like it might be related: https://ask.fedoraproject.org/en/question/80389/cannot-open-luks-container-with-rescue-initramfs/ Rescue gets generated without -H by default, and the standard with it. I never noticed an issue because I'm using the default keyboard layout. That's good enough for me; going to add -H back in.
