Okay interesting! I have not seen that error yet... I wonder if adding
'AutoReqProv: no' to the kernel-debuginfo subpackage (like the
kernel-devel subpackage) would avoid that for rpm 4.20.0... Probably not
that big of a deal if it is resolved with rpm 6.0.1 but it would be good
to avoid as many corner cases as possible.

Cheers,
Nathan
