Subject: [PATCH] 01fips: run sha512hmac from directory HMAC file directory
That way, the HMAC file can contain a relative path instead of an
absolute one. The issue is that right now the kernel RPM bakes the
`/boot/vmlinuz-${kver}` path into the HMAC file which poses an issue for
rpm-ostree systems (and any other system where the kernel isn't simply
in the top-level `/boot`.
For now, we're hacking around this in rpm-ostree:
https://github.com/coreos/rpm-ostree/pull/1934
Though I'd like to propose the same change in the kernel spec file.
