Do you mean that using this will not work?
IMA_KEXEC_IMAGE="${IMA_KEXEC_IMAGE:-/boot/vmlinuz-$(uname -r)}"
I don't understand that as I'm able to set variables even I run some tests in
dracut.

Also writing same docs doc on 2 places is not good. High level info should go to
README.md, implementation details to shell script.

Please hold on with posting new version. I have several fixes, thus I'd like to
send it after we sort this (trying to save you time).

Kind regards,
Petr
